Numerical computations on the zeros of the Euler double zeta-function II

Abstract

We study the behavior of zero-divisors of the double zeta-function ${\zeta }_2(s_1,s_2)$. In our former paper \cite{MatSho14} we studied the case $s_1=s_2$, but in the present paper we consider the more general two variable situation. We carry out numerical computations in order to trace the behavior of zero-divisors. We observe that some divisors approach the points with $s_2=0$, while other divisors approach the points which are solutions of $\zeta (s_2)=1$.
