Abstract:In this paper, we consider certain double polylogarithms and the ordinary polylogarithm of complex variables, and introduce a method of producing functional relations among them. Furthermore we consider tex:\chi-analogues of them. These functional relations can be regarded as polylogarithmic generalizations of the known relations between the Mordell-Tornheim double zeta-function and the Riemann zeta-function, and their character analogues, which were studied by the authors.
