Spirals of Riemann’s Zeta-Function — Curvature, Denseness and Universality
Published online by Cambridge University Press: 05 October 2023
Abstract
This paper deals with applications of Voronin’s universality theorem for the Riemann zeta-function $\zeta$. Among other results we prove that every plane smooth curve appears up to a small error in the curve generated by the values
$\zeta(\sigma+it)$ for real t where
$\sigma\in(1/2,1)$ is fixed. In this sense, the values of the zeta-function on any such vertical line provides an atlas for plane curves. In the same framework, we study the curvature of curves generated from
$\zeta(\sigma+it)$ when
$\sigma>1/2$ and we show that there is a connection with the zeros of
$\zeta'(\sigma+it)$. Moreover, we clarify under which conditions the real and the imaginary part of the zeta-function are jointly universal.
