Abstract
In this paper, we present some new identities for multiple polylogarithm functions by using the methods of iterated integral computations of logarithm functions. Then, by applying these formulas obtained, we establish several duality formulas for Arakawa–Kaneko zeta values and Kaneko–Tsumura \(\eta \)-values. At the end of the paper, we study a variant of Kaneko–Tsumura \(\eta \)-function with r-complex variables and establish two formulas about the values of this variant; these two formulas were proved previously by Yamamoto.
