On the Hurwitz Zeta Functions with Algebraic Irrational Parameter
A. Balčiūnas, A. Dubickas, A. Laurinčikas Institute of Mathematics, Vilnius University
Abstract:
It is well known that the Hurwitz zeta function $\zeta(s,\alpha)$ with rational or transcendental parameter $\alpha$ is universal in the sense of Voronin, i.e., a wide class of analytic functions can be approximated by the shifts $\zeta(s+i\tau,\alpha)$, $\tau\in \mathbb R$. The case of algebraic irrational $\alpha$ is still an open problem. It is proved that there exists a nonempty closed set of analytic functions that can be approximated by shifts $\zeta(s+i\tau,\alpha)$ with algebraic irrational $\alpha$.
Keywords:
algebraic irrational number, Hurwitz zeta function, limit theorem, universality.
