Introduction

Apéry numbers, named after the French mathematician Roger Apéry, are a sequence of integers that have garnered significant attention in the realm of number theory. These numbers have been extensively studied due to their connections to various mathematical concepts, including the Riemann zeta function, the distribution of prime numbers, and the properties of Bernoulli numbers. In this article, we will delve into a recently discovered formula for Apéry numbers, which appears to be a novel and intriguing identity.

Background on Apéry Numbers

Apéry numbers are defined as the coefficients of the expansion of the Riemann zeta function at negative integers. Specifically, the Apéry number $a_n$ is given by the formula:

a_n = \frac{1}{(2\pi i)^2} \oint_{\gamma} \frac{1}{\zeta(s)} \frac{d}{ds} \left( \frac{1}{\zeta(s+1)} \right) ds

where $\gamma$ is a contour that encircles the negative real axis. This definition provides a clear connection between Apéry numbers and the Riemann zeta function, which has far-reaching implications for number theory.

The New Formula for Apéry Numbers

In recent research, a new formula for Apéry numbers has been discovered, which appears to be a novel and intriguing identity. The formula is given by:

a_n = \sum_{i=0}^n \sum_{j=0}^n {n \choose i}^2 {n \choose j}^2{i+j \choose i}.

This formula seems to be a combination of binomial coefficients and a summation over two indices, $i$ and $j$ . The presence of binomial coefficients suggests a connection to combinatorial identities, while the summation over two indices hints at a deeper algebraic structure.

Properties of the New Formula

To gain a deeper understanding of the new formula, we need to examine its properties and behavior. One of the first questions to ask is whether the formula is valid for all values of $n$ . A quick analysis reveals that the formula is indeed valid for all non-negative integers $n$ .

Another important property of the formula is its computational complexity. The formula involves a double summation over binomial coefficients, which can be computationally intensive for large values of $n$ . However, the formula can be simplified using various combinatorial identities, which can reduce the computational complexity.

Connections to Other Mathematical Concepts

The new formula for Apéry numbers has connections to various other mathematical concepts, including Bernoulli numbers, the Riemann zeta function, and the properties of prime numbers. These connections provide a deeper understanding of the underlying structure of Apéry numbers and highlight the importance of this sequence in number theory.

Open Questions and Future Research Directions

While the new formula for Apéry numbers provides a novel and intriguing identity, there are still many open questions and research directions to explore. Some of the key questions include:

Can the formula be generalized to other sequences of integers?
Are there any connections between the formula and other areas of mathematics, such as algebraic geometry or representation theory?
Can the formula be used to derive new results in number theory, such as bounds on the distribution of prime numbers?

Conclusion

In conclusion, the new formula for Apéry numbers provides a novel and intriguing identity that has connections to various other mathematical concepts. The formula has been shown to be valid for all non-negative integers $n$ and has a computational complexity that can be reduced using combinatorial identities. While there are still many open questions and research directions to explore, the formula has the potential to provide new insights into the properties of Apéry numbers and the underlying structure of number theory.
