Staff Introduction

OHNO, Yasuo / Guest Professor

I am interested in number theory, combinatorics, topology, graph theory, and related topics. Especially, relations among various kind of zeta functions and their special values are topics of continuing interest. My current research is mainly on multiple zeta values/functions and related topics, examples of which include Arakawa-Kaneko zeta functions, poly-Bernoulli numbers, binary cubic forms, and digraphs.
