Euler's work on prime numbers

Definition

Euler's work on prime numbers refers to his groundbreaking contributions that established key relationships between primes and various mathematical functions. He introduced the Euler product formula, connecting the distribution of prime numbers to the Riemann zeta function. This connection not only deepened the understanding of prime numbers but also laid foundational work for future research in number theory.
