Abstract [eng] |
Let s be a complex variable, and a be a periodic sequence of complex numbers. The periodic Hurwitz zeta-function is defined, for sigma > 1 and by analytic continuation elsewhere. We prove that the function is universal in the following sense. Let K be a compact subset of the strip with connected complement, and let the function f(s) be continuous on K and analytic in the interior of K. Than, for every epsilion > 0. |
