Abstract:
There exists many types of multiple zeta functions, for example, Euler-Zagier type, Mordell-Tornheim type, and so on. In our recent work, we introduced a combinatorial object called 2-colored rooted tree and multiple zeta function associated with it, and gave a unified interpretation to some multiple zeta functions. In this talk, we will review the idea of 2-colored rooted trees and present results on multiple zeta functions and values at positive integer points associated with 2-colored rooted trees.
