Universality of Zeta Function

Definition

The universality of the zeta function refers to the remarkable property that the Riemann zeta function can approximate any holomorphic function on certain regions of the complex plane when evaluated at points close to its zeros. This concept connects deeply with the distribution of the zeros of the zeta function and their implications for number theory, particularly in understanding prime distributions. As a result, it sheds light on fundamental connections between analysis, algebra, and geometry.
