Abstract: | Let q ≥ 3 be an integer, and χ be a Dirichlet character modulo q, L(s, χ) denote the Dirichlet L-function corresponding to χ. In this paper, we show some early information on the mean value of the Dirichlet L-functions and give some new identities for where a = 2, 3, or 4. Then we give general identities for the case that the integer a divides q t- 1. |
