Riemann Hypothesis—Why So Hard?

February 21, 2021


“If I were to awaken after having slept a thousand years, my first question would be: has the Riemann Hypothesis been proven?” — David Hilbert

Steklov Institute memorial page

Sergei Voronin was an expert in number theory, who studied the Riemann zeta function, but who sadly died young over twenty years ago. We discussed his amazing 1975 result about the Riemann zeta function here. Others call the result the amazing theorem. I (Dick) am getting old—I almost forgot that we did a post on his theorem again over four years ago.

Today I thought we would recall his theorem, sketch why the theorem is true, and then discuss some extensions.

Starting with Alan Turing we have been interested in universal objects. Turing famously proved that there are universal machines: these can simulate any other machine on any input. Martin Davis has an entire book on this subject.

Universal objects are basic to complexity theory. Besides Turing’s notion, a universal property is key to the definition of NP-complete. A set {S} in NP is NP-complete provided all other sets in NP can be reduced to {S} in polynomial time. Michael Nielsen once began a discussion of universality in this amusing fashion:

Imagine you’re shopping for a new car, and the salesperson says, “Did you know, this car doesn’t just drive on the road.” “Oh?” you reply. “Yeah, you can also use it to do other things. For instance, it folds up to make a pretty good bicycle. And it folds out to make a first-rate airplane. Oh, and when submerged it works as a submarine. And it’s a spaceship too!”

Voronin’s Insight

In 1975 Voronin had the brilliant insight that the Riemann zeta {\zeta(s)} function has an interesting universality property. Roughly speaking, it says that a wide class of analytic functions can be approximated by shifts {\zeta(s+it)} with real {t}. Recall

\displaystyle  \zeta(s) = \sum_{n=1}^\infty \frac{1}{n^s}

for {\Re(s) >1}, and it has an analytic extension for all other values but {s=1}.

The intense interest in the {\zeta(s)} function started in 1859 with Bernhard Riemann’s breakthrough article. This was the first statement of what we call the Riemann Hypothesis (RH).

In over a century of research on RH before Voronin’s theorem, many identities, many results, many theorems were proved about the zeta function. But none saw that the {\zeta(s)} function was universal before Voronin. Given the zeta function’s importance in understanding the structure of prime numbers this seems to be surprising.

Before we define the universal property I thought it might be useful to state a related property that the {\zeta(s)} function has:

Theorem 1 Suppose that {P} is a polynomial so that for all {s},

\displaystyle  P\left(\zeta(s), \zeta{'}(s),\dots,\zeta^{(m)}(s) \right) = 0.

Then {P} is identically zero.

Since {s} is a single variable, this says that {\zeta(s)} and its derivatives {\zeta'(s)} and {\zeta''(s) \dots } do not satisfy any polynomial relationship. This means intuitively that {\zeta(s)} must be hypertranscendental. Let’s now make this formal.

Voronin’s Theorem

Here is his theorem:

Theorem 2 Let {0<r<1/4}. Let {f(s)} be an analytic function that never is zero for {|s| \le r}. Then for any {\epsilon>0} there is a real {t} so that

\displaystyle  \max_{\left | s \right | \leq r} \left | \zeta(s + \frac{3}{4} + i t) - f(s) \right | < \epsilon.

See the paper “Zeroes of the Riemann zeta-function and its universality,” by Ramunas Garunkstis, Antanas Laurincikas, and Renata Macaitiene, for a detailed modern discussion of his theorem.


Note that the theorem is not constructive. However, the values of {t} that work have a positive density—there are lots of them. Also note the restriction that {f(s)} is never zero is critical. Otherwise one would be able to show that the Riemann Hypothesis is false. In 2003, Garunkstis et al. did prove a constructive version, in a paper titled, “Effective Uniform Approximation By The Riemann Zeta-Function.”

Voronin’s Proof

The key insight is to combine two properties of the zeta {\zeta(s)} function: The usual definition with the Euler product. Recall the Riemann zeta-function has an Euler product expression

\displaystyle  \zeta(s) = \prod_p \frac{1}{1-p^{-s}}.

where {p} runs over prime numbers. This is valid only in the region {\Re(s) > 1}, but it makes sense in a approximate sense in the critical strip:

\displaystyle  1/2 < \Re(s) < 1.

Then take logarithms and since {\log(p)} are linearly independent over {Q}, we can apply the Kronecker approximation theorem to obtain that any target function {f(s)} can be approximated by the above finite truncation. This is the basic structure of the proof.

Open Problems

Voronin’s insight was immediately interesting to number theorists. Many found new methods for proving universality and for extending it to other functions. Some methods work for all zeta-functions defined by Euler products. See this survey by Kohji Matsumoto and a recent paper
by Hafedh Herichi and Michel Lapidus, the latter titled “Quantized Number Theory, Fractal Strings and the Riemann Hypothesis: From Spectral Operators to Phase Transitions and Universality.”

Perhaps the most interesting question is:

Can universality be used to finally unravel the RH?

See Paul Gauthier’s 2014 IAS talk, “Universality and the Riemann Hypothesis,” for some ideas.

    I’m really proud of have been working with you in a paper about the Riemann Hypothesis. Unfortunately, we have stopped the communication, but I hope some day we can finally continue on this. From our interchange, I learned a lot, principally in how to organize better the ideas (I need to learn more on that). You prefer to be only mentioned in the acknowledgements, that’s why I have to remove all your contributions and only pick some tiny things from our collaboration (for just to be honest with you). I wish that you could know that my invitation to work together on this is still open: this work can be improved much more until make it a perfect and verified proof (this has not been validated yet). This is all I have moved on these few past weeks:

    Nice introductory article for the general reader in the theory of universality of the Riemann zeta function. One comment I have is that on the last paragraph on “Open Problems” the last phrase is not typed properly, I guess you meant to say: “ See Khoji’s Matsumoto’s survey and also the work done by Hafedh Herichi and Michel Lapidus on quantizing the universality theorem of Voronin”. I suggest to fix this phrase, since in his survey, K. Matsumoto does not discuss the research work of Herichi and Lapidus on a quantum analog of the universality theorem of Voronin involving using truncated spectral operators. Overall a very nice art introductory article !

    There is universality. It is “topological quantization” where “critical line” is a boundary of certain manifold and pole at 1 is Arnold tongue. I think I’m 3 theorem away from RH. First — If a submanifold is constructable by local zeta function(“emergent acting potential” so to say) and has equalized action to outside and inside to zero, then meeting “super-secret” condition results in existence of self-adjoint unbounded operator that constructs this manifold out of nothingness, it emerges, so to say, and this operator is linear. Also, it cannot be wandering. Second — For any topological cycle on “topological quanta” there does exist algebraic cycle that has certain rotation number(zero maybe? I’m a bit struggling with this condition) if a set of topological quanta is closed for particular topological cycle. Using the fact that “critical line” is a boundary of a manifold we show that critical line is “fixable”(we can repair it) and bring zeroes to its place by moving zeroes in relation to each other, it is like if RH is false then we can come up with better function that does the same and has its all zeroes on the line, this criteria is super easy. Third — there does exist cycle on “topological quanta” of a form p + 2 = p (twin prime conjecture) and it occurs infinitely often. Assuming that it is false we show that in this case Arnold tongue would make pole at 1 finite value and therefore strip RZF of its analytic continuation. And then we state that pole at 1 implies that our set of “topological quanta” is a self-boundary of certain manifold that gets created by RZF in an act of “self-emergence” and that if any such cycle P+n1=n2 would fail it would imply that n1 or n2 is not in N. I call it “criteria of incremental stability”. You can imagine natural line to be a topology based vector(with of quanta 1 and repeat it infinitely often for all numbers on the vector) and prime numbers to be a directional quanta of this vector in all possible directions and for each P there does exist similar rerepresentaion on quanta of this quantized vector and it all unites in continuous “thing”. It is all going to be super-confusing, I know, but imagine zero-knowledge proofs of action in dynamical systems. You give me DS and claim that you have seen action in it. How do I verify without obtaining knowledge about your proof that it is right? I’m just checking that “our topological quanta” coincide that’s it. And PvsNP is harder then this because it requires measuring “density of cycles” in all possible ways, I think I’m going to give up on P!=NP because of this. By the end of this year I will, maybe, post my paper or go to prison for criticizing Putin. I just have no formal education and don’t think that anybody will be interested in a reading of my fabrication, still the process of making one is quite interesting!

    Zeta universality does have the proof of P vs NP. However, writing it out in detail is NP hard!

  5. Why is P vs NP so important? permalink

    If NP complete languages are subset of Indexed languages which are subset of Context sensitive languages which are subset of Turing complete languages which humans are capable of why is P vs NP important?

    Short Note on the Riemann Hypothesis

    Robin criterion states that the Riemann Hypothesis is true if and only if the inequality $\sigma(n) 5040$, where $\sigma(n)$ is the sum-of-divisors function and $\gamma \approx 0.57721$ is the Euler-Mascheroni constant. This is known as the Robin inequality. We know that the Robin inequality is true for all $n > 5040$ which are not divisible by $2$. In addition, we prove the Robin inequality is true for all $n > 5040$ which are divisible by $2$. In this way, we show the Robin inequality is true for all $n > 5040$ and thus, the Riemann Hypothesis is true.

    The Holy Grail of Mathematics

    A trustworthy proof for the Riemann hypothesis has been considered as the Holy Grail of Mathematics by several authors. The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. Let Q be the set of prime numbers q_{n} satisfying the inequality \prod_{q \leq q_{n}} \frac{q}{q-1} \geq e^{\gamma} \cdot \log\theta(q_{n}) with the product extending over all prime numbers q that are less than or equal to q_{n}, where \gamma \approx 0.57721 is the Euler-Mascheroni constant, \theta(x) is the Chebyshev function and \log is the natural logarithm. If the Riemann hypothesis is false, then there are infinitely many prime numbers q_{n} outside and inside of Q. In this note, we obtain a contradiction when we assume that there are infinitely many prime numbers q_{n} outside of Q. By reductio ad absurdum, we prove that the Riemann hypothesis is true.

    Trivial results extended on the paper:

    https://dx.doi.org/10.13140/RG.2.2.15964.05763


    Note that,

    \frac{z}{\log(z)} \leq \frac{1 + z}{2} + \frac{1}{\log(z)}

    since for x \geq -0.9:

    \frac{2}{2 + x} \leq \frac{\log(1 + x)}{x}

    where z = \frac{\theta(q_{k + j})}{\theta(q_{k})}.

    However, we know that

    \frac{1 + z}{2} + \frac{1}{\log(z)} \leq \frac{q_{k + 1}}{j \cdot \log(\theta(q_{k}))}

    for several values of z.

    Certainly, when z \leq 2 then,

    \frac{1}{\log(z)} < \frac{1}{2} + \frac{\theta(q_{k})}{\theta(q_{k + j}) - \theta(q_{k})}

    since for x \geq 1:

    \log(1 + \frac{1}{x}) \geq \frac{1}{x + 0.5}.

    In this way, we know that

    \frac{2 + z}{2} + \frac{\theta(q_{k})}{\theta(q_{k + j}) - \theta(q_{k})} \leq \frac{q_{k + 1}}{j \cdot \log(\theta(q_{k}))}

    for several values of z \leq 2 while q_{k} could be large enough.

    The End.

    Riemann hypothesis on odd perfect numbers

    The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. The Riemann hypothesis is considered by many to be the most important unsolved problem in pure mathematics. Let \sigma(n) denote the sum-of-divisors function \sigma(n)=\sum_{d \mid n} d. An integer n is perfect if \sigma(n)=2 \cdot n. It is unknown whether any odd perfect numbers exist. Leonhard Euler stated: “Whether \ldots there are any odd perfect numbers is a most difficult question”. We require the properties of superabundant numbers, that is to say left to right maxima of n \mapsto \frac{\sigma(n)}{n}. We also use Ramanujan’s old notes which were published in 1997 annotated by Jean-Louis Nicolas and Guy Robin. There are several statements equivalent to the famous Riemann hypothesis. In this note, conditional on Riemann hypothesis, we prove that there are not infinitely many odd perfect numbers.

    Riemann hypothesis on odd perfect numbers

    The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. The Riemann hypothesis is considered by many to be the most important unsolved problem in pure mathematics. Let \sigma(n) denote the sum-of-divisors function \sigma(n)=\sum_{d \mid n} d. An integer n is perfect if \sigma(n)=2 \cdot n. It is unknown whether any odd perfect numbers exist. Leonhard Euler stated: “Whether \ldots there are any odd perfect numbers is a most difficult question”. We require the properties of superabundant numbers, that is to say left to right maxima of n \mapsto \frac{\sigma(n)}{n}. We also use Robin’s criterion and Ramanujan’s old notes which were published in 1997 annotated by Jean-Louis Nicolas and Guy Robin. There are several statements equivalent to the famous Riemann hypothesis. In this note, conditional on Riemann hypothesis, we prove that there is no odd perfect number.

    Robin’s Inequality for Superabundant Numbers (A Millennium Prize Problem)

    The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. There are several statements equivalent to the famous Riemann hypothesis. Robin’s criterion states that the Riemann hypothesis is true if and only if the inequality \sigma(n) < e^{\gamma} \cdot n \cdot \log \log n holds for all natural numbers n \geq 5041, where \sigma(n) is the sum-of-divisors function of n, \gamma \approx 0.57721 is the Euler-Mascheroni constant and \log is the natural logarithm. We require the properties of superabundant numbers, that is to say left to right maxima of n \mapsto \frac{\sigma(n)}{n}. It is well-known that the smallest counterexample of the Robin's inequality greater than 5040 must be a superabundant number. In this note, we prove that the Robin's inequality holds for all superabundant numbers greater than 5040. By reductio ad absurdum, we prove that the Riemann hypothesis is true.

    On Solé and Planat criterion for the Riemann hypothesis
    (A Millennium Prize Problem)

    The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. This is one of the Clay Mathematics Institute’s Millennium Prize Problems. There are several statements equivalent to the famous Riemann hypothesis. In 2011, Solé and Planat stated that the Riemann hypothesis is true if and only if the inequality \zeta(2) \cdot \prod_{p\leq p_{k}} (1+\frac{1}{p}) > e^{\gamma} \cdot \log \theta(p_{k}) holds for all prime numbers p_{k} \geq 5, where \theta(x) is the Chebyshev function, \gamma \approx 0.57721 is the Euler-Mascheroni constant, \zeta(x) is the Riemann zeta function and \log is the natural logarithm. Let \sigma(n) denote the sum-of-divisors function of n. We also require the properties of superabundant numbers, that is to say left to right maxima of n \mapsto \frac{\sigma(n)}{n}. In this note, using Solé and Planat criterion on superabundant numbers, we prove that the Riemann hypothesis is true.

    Riemann Hypothesis on Grönwall’s Function (A Millennium Prize Problem)

    Grönwall’s function G is defined for all natural numbers n > 1 by G(n)=\frac{\sigma(n)}{n \cdot \log \log n} where \sigma(n) is the sum of the divisors of n and \log is the natural logaritm. We require the properties of extremely abundant numbers, that is to say left to right maxima of n \mapsto G(n). We also use the colossally abundant and hyper abundant numbers. A number n is said to be colossally abundant if, for some \epsilon > 0, \frac{\sigma(n)}{n^{1 + \epsilon}} \geq \frac{\sigma(m)}{m^{1 + \epsilon}} for all m > 1. Let us call hyper abundant an integer n for which there exists u > 0 such that \frac{\sigma(n)}{n \cdot (\log n)^{u}} \geq \frac{\sigma(m)}{m \cdot (\log m)^{u}} for all m > 1. The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. It is considered by many to be the most important unsolved problem in pure mathematics. There are several statements equivalent to the famous Riemann hypothesis. We state that the Riemann hypothesis is true if and only if there exist infinitely many consecutive colossally abundant numbers 3 \leq N < N' such that G(N) \leq G(N'). In addition, we prove that the Riemann hypothesis is true when there exist infinitely many hyper abundant numbers n with any parameter u \approx 1.

    On the nontrivial zeros of the Riemann zeta function
    (A Millennium Prize Problem)

    The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \frac{1}{2}. It is considered by many to be the most important unsolved problem in pure mathematics. There are several statements equivalent to the famous Riemann hypothesis. In 2011, Solé and Planat stated that, the Riemann hypothesis is true if and only if the inequality \zeta(2) \cdot \prod_{p\leq x} (1+\frac{1}{p}) > e^{\gamma} \cdot \log \theta(x) holds for all x \geq 5, where \theta(x) is the first Chebyshev function, \gamma \approx 0.57721 is the Euler-Mascheroni constant, \zeta(x) is the Riemann zeta function and \log is the natural logarithm. In this note, using Solé and Planat criterion, we prove that, when the Riemann hypothesis is false, then there are infinitely many natural numbers x for which \frac{\log x}{\sqrt{x}} - \frac{10}{\sqrt{x}} + 2 \cdot \log x + \varepsilon \cdot \log x \leq 2.062 could be satisfied for some \varepsilon > 0. Since the inequality \frac{\log x}{\sqrt{x}} - \frac{10}{\sqrt{x}} + 2 \cdot \log x + \varepsilon \cdot \log x \leq 2.062 never holds for every \varepsilon > 0 and large enough x, then the Riemann hypothesis is true by principle of non-contradiction.

    The smallest gap between primes
    (Twin Prime Conjecture)

    A prime gap is the difference between two successive prime numbers. Two is the smallest possible gap between primes. A twin prime is a prime that has a prime gap of two. The twin prime conjecture states that there are infinitely many twin primes. This conjecture has been one of the great open problems in number theory for many years. In May 2013, the popular Yitang Zhang’s paper was accepted by the journal Annals of Mathematics where it was announced that for some integer N that is less than 70 million, there are infinitely many pairs of primes that differ by N. A few months later, James Maynard gave a different proof of Yitang Zhang’s theorem and showed that there are infinitely many prime gaps with size of at most 600. A collaborative effort in the Polymath Project, led by Terence Tao, reduced to the lower bound 246 just using Zhang and Maynard results as the main theoretical background. In this note, using arithmetic operations, we prove that the twin prime conjecture is true. Indeed, this is a trivial and short note very easy to check and understand which is a breakthrough result at the same time.

    The Riemann Hypothesis and Twin Prime Conjecture are close related.

    Homogeneous Diophantine equation of degree two in NP-complete

    In mathematics, a Diophantine equation is a polynomial equation, usually involving two or more unknowns, such that the only solutions of interest are the integer ones. A homogeneous Diophantine equation is a Diophantine equation that is defined by a homogeneous polynomial. Solving a homogeneous Diophantine equation is generally a very difficult problem. However, homogeneous Diophantine equations of degree two are considered easier to solve. Certainly, using the Hasse principle we may able to decide whether a homogeneous Diophantine equation of degree two has an integer solution. We prove that this decision problem is actually in \textit{NP--complete} under the constraint that the each variable is required to be evaluated in \{0, 1\}.

    Assuming the Birch and Swinnerton-Dyer conjecture, n is a congruent number if and only if the number of triplets of integers (x, y, z) satisfying 2*x^{2} + y^{2} + 8*z^{2} = n is twice the number of triplets satisfying 2*x^{2} + y^{2} + 32*z^{2} = n. (see Tunnell’s theorem).

    Counting solutions of the homogeneous Diophantine equations of degree two seems to be a problem in sharp-P-complete (see my previous posts).

    Detecting whether n is congruent or not seems to be a problem in NP: congruent numbers could be easily checked by a congruum since every congruent number is a product of a congruum and the square of a rational number.

    Under the assumption that P = NP and P \neq sharp-P, is Birch and Swinnerton-Dyer conjecture indeed false?

    Sharp-P and the Birch and Swinnerton-Dyer conjecture

    Assuming the Birch and Swinnerton-Dyer conjecture, an odd square-free integer n is a congruent number if and only if the number of triplets of integers (x, y, z) satisfying 2 \cdot x^{2} + y^{2} + 8 \cdot z^{2} = n is twice the number of triplets satisfying 2 \cdot x^{2} + y^{2} + 32 \cdot z^{2} = n due to Tunnell’s theorem. However, we show these equations are instances of a variant of counting solutions of the homogeneous Diophantine equations of degree two which is a \textit{\#P--complete} problem. Deciding whether n is congruent or not is a problem in NP since congruent numbers could be easily checked by a congruum, because of every congruent number is a product of a congruum and the square of a rational number. We conjecture that if P = NP and FP \neq \#P, then the Birch and Swinnerton-Dyer conjecture would be false.

However, we show these equations are instances of a variant of counting solutions of the homogeneous Diophantine equations of degree two which is a \textit{\#P--complete} problem. Deciding whether n is congruent or not is a problem in NP since congruent numbers could be easily checked by a congruum, because of every congruent number is a product of a congruum and the square of a rational number. Certainly, every congruum is in the form of 4 \cdot m \cdot n \cdot (m^{2}-n^{2}) (with m>n), where m and n are two distinct positive integers. We conjecture that if P = NP and FP \neq \#P, then the Birch and Swinnerton-Dyer conjecture would be false.

A homogeneous Diophantine equation is a Diophantine equation that is defined by a homogeneous polynomial. Solving a homogeneous Diophantine equation is generally a very difficult problem. However, homogeneous Diophantine equations of degree two are considered easier to solve. Certainly, using the Hasse principle we may able to decide whether a homogeneous Diophantine equation of degree two has an integer solution: we are able to reject an instance when there is no solution reducing the equation modulo p. We prove that this decision problem is actually in NP-complete under the constraints that all solutions contain only positive integers which are actually a residue of modulo a single positive integer. This problem remains in NP-complete even when all the coefficients are non-negative.

    Note on the Riemann Hypothesis: International Conference on Recent Developments in Mathematics (ICRDM 2022)

    The Riemann Hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 1/2. In 1984, Guy Robin stated a new criterion for the Riemann Hypothesis. We prove the Riemann Hypothesis is true using the Robin’s criterion.

    Deep on Goldbach’s conjecture

    Goldbach’s conjecture is one of the most difficult unsolved problems in mathematics. This states that every even natural number greater than 2 is the sum of two prime numbers. In 1973, Chen Jingrun proved that every sufficiently large even number can be written as the sum of either two primes, or a prime and a semiprime (the product of two primes). In 2015, Tomohiro Yamada, using the Chen’s theorem, showed that every even number > \exp \exp 36 can be represented as the sum of a prime and a product of at most two primes. In 2002, Ying Chun Cai proved that every sufficiently large even integer N is equal to p + P_{2}, where P_{2} is an almost prime with at most two prime factors and p \leq N^{0.95} is a prime number. In this note, we prove that for every even number N \geq 32, if there is a prime p and a natural number m such that n < p < N - 1, p + m = N, N \gg \sigma(m) and p is coprime with m, then m is necessarily a prime number when \sigma(m) is the sum-of-divisors function of m, N = 2 \cdot n and \gg means "much greater than''. Indeed, this is a trivial and short note very easy to check and understand which is a breakthrough result at the same time.

    This is a release of the binaries of a project which solves an instance of the problem 3SAT in O(m^{2} \cdot n^{4}) where n is the number of variables and m is the number of clauses. The exponent in the algorithm is not very good, so this release would be only feasible for small values of n.

    The original Boolean formula is translated to a homogeneous polynomial of degree 2. Finally, we solve it using dynamic programming based on the implementation of the problem Subset Sum. The reduction is simplified in order to obtain efficiency. Mutable objects need to be changed.

    Note that, the problem could be solved by the Hasse-Minkowski theorem. We know the solution on dynamic programming of the problem Subset Sum could be exponential. However, in our polynomial time reduction the problem remains polynomial over the number of variables.

    Directed Hamiltonian Path

    Instance: A directed graph G = (V, E) of n vertices, such that each vertex is labeled with a unique integer from 1 to n. A Hamiltonian path is a simple path (with no repeated nodes) such that this one contains all the vertices in V.

    Question: Is there a Hamiltonian path from 1 to n in the graph G?

    Note: This problem is NP-complete.

    We solve this problem in polynomial time in order O(E*V^{2}). If there is any NP-complete solvable in polynomial time, then P = NP.

    We based our algorithm on this property of the Euler–Mascheroni constant:

    H_{n}=\ln n+\gamma +{\frac {1}{2n}}-\varepsilon _{n}

    where H_{n} is the Harmonic series until n, \gamma \approx 0.5772 is the Euler–Mascheroni constant and 0\leq \varepsilon _{n}\leq 1/8n^{2} which approaches 0 as n goes to infinity. Note that, we use the first 170000 digits of \gamma, so this could fail for n large enough (However, Seungmin Kim & Ian Cutress found the first 600000000100 digits on May 26, 2020).

    Homogeneous Diophantine equation of degree two in NP-complete

    We prove the following problem is NP-complete (in a trivial way):

    “Decide whether a homogeneous Diophantine equations of degree two has integer solutions which are actually residues of modulo a single positive integer.”

    However, homogeneous Diophantine equations of degree two are considered easier to solve. Certainly, using the Hasse principle we may able to decide whether a homogeneous Diophantine equation of degree two has an integer solution: we are capable to reject an instance when there is no solution reducing the equation modulo p.

    In this way, we prove that this problem is also in coNP since the previous mentioned prime p can be polynomially bounded by the instance and checking whether an assignment is not a solution can be done in polynomial time.

    Consequently, we show that NP = coNP in a trivial way since any NP-complete problem in coNP is pretty enough evidence for this result.

    Homogeneous Diophantine equation of degree two in NP-complete

    Extended comments (specifically for you in case you might like to go deep):

    The Hasse principle guarantee if there is a rational solution, then there are solutions modulo every prime p. In this way, if there is no solution reducing the equation modulo some prime p, then the equation has not a rational solution. There is a trivial mechanism for transforming rational solutions to integer solutions residues some prime, so there are not integer solutions when there is no solution reducing the equation modulo for some prime p. I have realized that this disqualification (the equivalent string to a certificate but in coNP) prime p tends to be bounded by the coefficients of the equation and checking whether
    the equation has not a p-adic solution could be solved in polynomial time. The existence of this disqualification for every homogeneous Diophantine equations of degree two which has not integer solution makes this NP-complete problem in coNP (this implies that NP = coNP). This is a very short and clean result:

    Deep on Goldbach’s conjecture

    Goldbach’s conjecture is one of the most difficult unsolved problems in mathematics. This states that every even natural number greater than 2 is the sum of two prime numbers. The Goldbach’s conjecture has been verified for every even number N \leq 4 \cdot 10^{18}. In this note, we prove that for every even number N \geq 4 \cdot 10^{18}, if there is a prime p and a natural number m such that n < p < N - 1, p + m = N, \frac{N}{\sigma(m)} + n^{0.889} + 1 + \frac{m - 1}{2} \geq n and p is coprime with m, then m is necessarily a prime number when N = 2 \cdot n and \sigma(m) is the sum-of-divisors function of m. The previous inequality \frac{N}{\sigma(m)} + n^{0.889} + 1 + \frac{m - 1}{2} \geq n holds whenever \frac{N}{e^{\gamma} \cdot m \cdot \log \log m} + n^{0.889} + 1 + \frac{m - 1}{2} \geq n also holds and m \geq 11 is an odd number, where \gamma \approx 0.57721 is the Euler-Mascheroni constant and \log is the natural logarithm. This implies that the Goldbach's conjecture is true when the Riemann hypothesis is true.

    Frequently, people push you to find a practical applications for any of your pure mathematical drafts and in most cases those interactions become positive.
    That is the case of my recent approach on the Goldbach’s conjecture:

    https://dx.doi.org/10.13140/RG.2.2.13146.41925

    It is better to give a naive explanation to reach more curious audience about it:

    Suppose that some teenager argue that 11 is not prime and my paper got published. Then, you only have to convince him that 29 is prime and 40 is an even number. After that, you only have to show him that

    40 / (1.7811 * 11 * ln(ln(11))) + 20^(0.889) + 1 + (11 – 1) / 2 ≈ 22 ≥ 20

    since your opponent truly believes that my paper is correct. Of course, I proved this only for all even numbers N ≥ 410^(18). Certainly, this comment has only an educative goal and does not pretend to be a rigorous math evidence (40 is much lesser than 410^(18)).

    I suspect that this result could be extended for a wide range of even numbers lesser than 4*10^(18). For that reason, I decided to answer people’s question with simple even numbers such as 40. However, my intuition requires another paper maybe more difficult than this one or a feasible computer validation.

    However, in case of being correct this can be applied for finding large prime numbers with a lower computational cost. For example, we can start the search from a well-known and large Mersenne prime and find more large prime numbers relative close to this big number using a very feasible time complexity.

    Homogeneous Diophantine equation of degree two in NP-complete

    We say that a quadratic form f has a solution over a field K if this is a homogeneous degree-2 polynomial with coefficients in K and the values of the solution are in K. The theorem Hasse-Minkowski states that a quadratic form f has a solution over Q if and only if f has solution over R and Qp for all primes p. In a quadratic form, we can transform rational solutions into integer solutions. Based on this known result, we could consider that the problem of deciding whether a quadratic form has a solution over Z is a coNP problem. Certainly, using the Hasse principle we may able to reject an instance when there is no solution reducing the equation modulo p. However, we show that the problem of deciding whether a quadratic form has a solution over Zn for a single natural number n is indeed in NP-complete: any NP-complete in coNP implies that NP=coNP. Perhaps, this manuscript can help us in reveal more properties in details about the P vs NP problem.

    I hope the following statements could help to move beyond the current frontiers on the smallest gap prime in probably a similar way it did the Zhang and Maynard results:

    For all x > 1 and a \geq 0, we define the function:

    H_{a}(x) = \log(\frac{x}{x - 1}) - \frac{1}{x + a} + \log(\frac{x^{2} - \sqrt[\leftroot{-3}\uproot{7}\log(x) + 1]{x}}{x^2})

    We have H_{2}(x) is lesser than 0 and H_{4}(x) is greater than 0 for large enough x based on finding their roots using fast computation using the web site WolframAlpha which is an answer engine developed by Wolfram Research. We show that

    \sum_{p_{k} \geq p_{n}} H_{4}(p_{k}) \leq 0

    under the assumption that the Twin Prime Conjecture is false for a large enough nth prime p_{n}. Hence, by Reductio ad absurdum, the Twin Prime Conjecture is true.

    The P versus NP problem:

    We show that the problem of deciding whether a homogeneous Diophantine equations of degree 2 has a solution residues of modulo a single positive integer is in \textit{NP-complete}. There are libraries that can solve homogeneous Diophantine equations of degree 2. For example, in Python, you can use the “pely” library to solve homogeneous Diophantine equations of degree 2.

    We show the \textit{NP--completeness} in the problem of deciding whether a homogeneous Diophantine equations of degree 2 has a solution residues of modulo a single positive integer. We could transform this algorithm to an optimization problem that is algorithmically practical solving P-Selective Sets on SAT instances that works better when both formulas have approximately the same number of variables and clauses. The whole algorithm is based on the problem of quadratic optimization without constraints which is feasible when we do not restrict the variables to be integers. Certainly, the conversion of a clause c_{i} = (a \oplus b) into a small piece of Homogeneous Diophantine Polynomial of degree two on residues of modulo 2

    P(x_{a}, x_{b}) = x_{a}^{2} - 2 \cdot x_{a} \cdot x_{b} + x_{b}^{2} = (x_{a} - x_{b})^{2}

    works for integers x_{a}, x_{b} \in \{0, 1\} and real values 0 \leq x_{a} \leq 1 and 0 \leq x_{b} \leq 1 at the same time, since the expression (x_{a} - x_{b})^{2} is maximized to the optimal value of 1 only on solutions in \{0, 1\} for both cases according to our described and explained reduction. We implement a software solution to this problem, specifically dealing with the problem \textit{P--Selective--SAT}, that runs feasible using the algorithm PRAXIS (PRincipal AXIS): PRAXIS is a gradient-free local optimization via the “principal-axis method” of Richard Brent.

    Indeed, I reduced SAT to solve a polynomial Diophantine equation of degree 2 (homogeneous). I submitted to a conference and a journal and obtained the same response: “it’s cute, but we don’t see any practical application”. Then, I realized that my polynomial time reduction works not only for integers but for real numbers as well. At the end, I noticed that SAT is equivalent to obtain the maximum value of polynomial of degree two. I tried to implement it, but global optimization is not very feasible for quadratic polynomials, so I changed it to local optimization and felt happy with the results.

    This the theoretical background which supported such previous implementation:

    SAT is as hard as solving Homogeneous Diophantine Equation of Degree Two

    P versus NP is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is P equal to NP? It was essentially mentioned in 1955 from a letter written by John Nash to the United States National Security Agency. However, a precise statement of the P versus NP problem was introduced independently by Stephen Cook and Leonid Levin. Since that date, all efforts to find a proof for this problem have failed. In mathematics, a Diophantine equation is a polynomial equation, usually involving two or more unknowns, such that the only solutions of interest are the integer ones. A homogeneous Diophantine equation is a Diophantine equation that is defined by a homogeneous polynomial. Solving a homogeneous Diophantine equation is generally a very difficult problem. However, homogeneous Diophantine equations of degree two are considered easier to solve. We prove that this decision problem is actually in NP-complete under the constraints that all solutions contain only positive integers which are actually residues of modulo a single positive integer.

    Thanks in advance….

    The twin prime conjecture appeared to be invincible through the years. Top mathematicians like Hardy and his colleague Littlewood, among others, couldn’t beat it during their whole career. Nevertheless, they achieved substantial advances that made the conjecture more famous and more tempted to prove. Even Erdős himself, famous for solving difficult problems, was engaged in solving this conjecture. This conjecture states that there are infinitely many primes separated by a gap of 2: for example, 3 and 5, 5 and 7, 11 and 13, etc. In ancient Greece, Euclid showed that there are infinitely many prime numbers, so it was not discarded the twin prime conjecture was also true. In April 2013, the Chinese-American Yitang Zhang announced that there are at least infinitely many primes separated by a gap of 70 million. This shocked everyone, since Yitang used one of the most difficult methods to achieve his result (he made an improvement to the Goldston–Graham–Pintz–Yıldırım result) and also he was considered an “unknown” number theorist in the international community of mathematicians at the time. Months later, a young man named James Maynard achieve to bound the gap to 600: this mathematician received the Fields medal in 2022 for this achievement and other contributions he made after it. Immediately, the best mathematicians in the world got together under the Polymath Project led by Terence (Terry) Tao who is one of the best current active mathematicians. In a joint effort over months they brought the gap down to 246 and since then, no significant progress has been made beyond. The author using a site (Wolfram Alpha) that links artificial intelligence and mathematics, achieved a calculation that concludes after certain arithmetic steps that the twin prime conjecture is actually true (i.e. he reduced the current gap from 246 to the minimum, which is 2, ending the quest to improve the result).

    In 1955, the well-known mathematician John Nash wrote to the United States National Security Agency about a problem that had major implications for security and scientific development. A short time later Gödel, one of the most important mathematical logicians, came to the same conclusion and wrote a letter to John von Neumann explaining about the same problem and its relation to computational and mathematical topics. John von Neumann had a successful career in this field at that time: unfortunately he promptly died of cancer and Gödel’s letter was never answered. It took decades later for the American mathematicians Stephen Cook and Russian Leonid Levin could be able to independently introduce and formulate this problem during the “scientific race” of the Cold War. The problem was called P versus NP and it consisted of knowing whether computers were capable or not of solving problems that seemed unfeasible with the computers of that time. The wheel of time passed and these problems are still not feasible to be solved by current computers despite being more powerful. The problem has been extensively studied and is now known to potentially cure cancer if a positive solution is found. Not only this, the disasters caused by the earthquakes in Syria and Turkey could have been predicted and avoided, artificial intelligence tools would achieve their full potential within the recent advances and would also have important industrial and social value since many current flow processes depend on computers. The author found a non-constructive solution (that is, focused on a theoretical answer rather than a practical one) that seems to be feasible not only in speed but also in memory efficiency.

    The Riemann hypothesis is considered the holy grail of mathematics. The eminent mathematician David Hilbert once said: “If I were to awaken after having slept a thousand years, my first question would be: has the Riemann Hypothesis been proven?” In 1913, Grönwall found what is known today as the Grönwall’s function. Years later, the great Ramanujan found that this function had a certain relationship with the Riemann hypothesis. Since then, Ramanujan began to study certain numbers of which his own tutor Hardy commented to a colleague, confessing: “Even Ramanujan could not make highly composite numbers interesting.” Ramanujan had a very long manuscript on highly composite numbers but some of it was not published until they were found stored in a Cambridge library at the end of the 20th century. During all those years, the prolific mathematician Erdős rediscovered the properties of these numbers and they began to be called colossally abundant numbers. The French mathematicians Robin and Nicolas developed during their research a closer relationship between colossally abundant numbers and the Riemann hypothesis. At the beginning of this century, Nicolas, who was also a close collaborator with Erdős, revealed the importance of an extraordinary number that he called hyper abundant number which belongs to the colossally abundant numbers. The author found another close relationship between the Riemman hypothesis and the colossally abundant numbers with hyper abundant numbers using the Grönwall’s function which announces that the Riemann hypothesis is indeed true.

  122. May 4, 2023 9:53 pm

    We prove that the Riemann hypothesis is true when there exist infinitely many hyper abundant numbers n with any parameter u ⪆ 1. We claim that there could be infinitely many hyper abundant numbers with any parameter u ⪆ 1 and thus, the Riemann hypothesis would be true.
