Bernoulli Zeta Function

Definition

The Bernoulli zeta function is a special function defined in terms of the Bernoulli numbers and has significant applications in number theory and K-Theory. It is a generalization of the Riemann zeta function, where it encodes information about the distribution of prime numbers and their relationships with algebraic objects. In K-Theory, the Bernoulli zeta function plays a crucial role in establishing connections between topological invariants and arithmetic properties.
