Upper bounds for the density of universality. II

Jörn Steuding (2005)

Acta Mathematica Universitatis Ostraviensis

Similarity:

We prove explicit upper bounds for the density of universality for Dirichlet series. This complements previous results [15]. Further, we discuss the same topic in the context of discrete universality. As an application we sharpen and generalize an estimate of Reich concerning small values of Dirichlet series on arithmetic progressions in the particular case of the Riemann zeta-function.

We investigate the singularities of a class of multiple L-functions considered by Akiyama and Ishikawa [2].
