Voronin Universality in several complex variables
arXiv:1809.03444
Abstract
We prove the Voronin universality theorem for the multiple Hurwitz zeta-function with rational or transcendental parameters in answering a question of Matsumoto. In particular this implies that the Euler-Zagier multiple zeta-function is universal in several complex variables and gives the first example of a Dirichlet series that is universal in more than one variable.
