本文利用三角和估值的指数偶方法,改进了张文鹏关于(?)L—函数的二次均值(?)│L(1/2+it,x)│~2的一个渐近公式.
In this paper we improve the asymptotic formula obtained by Zhang Wenpeng about the mean square value of Dirichlet L-functions:by using the method of exponential pairs for the trigonometric sum. We proved the following Theorem:Theorem For any mod q and real t ≥ 3 we haveWhere r is Euler's constant.
