Combinatorics of hyperplane arrangements and Witten zeta function at the origin
Kam Cheong Au, Kazuhiro Onodera
We introduce a new method that brings the combinatorics of hyperplane arrangements into the study of representation zeta functions of compact Lie groups. For the Witten zeta functi…

Mordell-Tornheim multiple zeta-functions, their integral analogues, and relations among multiple polylogarithms
Kohji Matsumoto, Kazuhiro Onodera, Dilip K. Sahoo
We study the asymptotic behavior of a multiple series of Mordell-Tornheim type and its integral analogue at x=0. Our approach is to show a relation between the multiple series and…

A functional relation for Tornheim's double zeta functions
Kazuhiro Onodera
In this paper, we generalize the partial fraction decomposition which is fundamental in the theory of multiple zeta values, and prove a relation between Tornheim's double zeta func…
