Abstract

We prove an explicit upper bound of the function , defined by the argument of Dirichlet L-functions attached to a primitive Dirichlet character (mod q > 1). An explicit upper bound of the function S(t), defined by the argument of the Riemann zeta-function, have been obtained by A. Fujii [1]. Our result is obtained by applying the idea of Fujii's result on S(t). The constant part of the explicit upper bound of in this paper does not depend on . Our proof does not cover the case q = 1 and indeed gives a better bound than the one of Fujii that covers the case q = 1.
