The prime zeta function is a mathematical function related to prime numbers and is defined as the infinite series: \[ P(s) = \sum_{p \text{ prime}} \frac{1}{p^s} \] where \( p \) runs over all prime numbers and \( s \) is a real number greater than 1.
P-adic L-functions are a concept in number theory and algebraic geometry that arises in the study of p-adic numbers and L-functions. They are closely related to both classical L-functions (like Riemann zeta functions and Dirichlet L-functions) and p-adic analysis.
The multiple zeta function is a generalization of the classical Riemann zeta function, which plays a significant role in number theory and mathematical analysis. The classical Riemann zeta function is defined for complex numbers \( s \) with real part greater than 1 as: \[ \zeta(s) = \sum_{n=1}^{\infty} \frac{1}{n^s}. \] The multiple zeta function extends this idea to multiple variables.

Montgomery's pair correlation conjecture is a conjecture in number theory related to the distribution of the zeros of the Riemann zeta function.
