利用解析方法以及Dedekind和的性质研究Dirichlet L-函数的一类特殊二次均值的计算问题,并给出均值∑x(-1)=1|L(1,χλ)|2的几个精确的计算公式,其中∑x(-1)=1表示对模q的所有偶特征求和,λ是模r的一个固定的奇特征,q及r为大于或等于3的整数且满足(r,q)=1。
Using the analytic method and the properties of Dedekind sums, the computational problems of one kind mean square value of Dirichlet L-functions are studied, several exact computational formulas are given for ∑x(-1)=1|L(1,χλ)|2, where the summation over all even charactersmod q,;t is a fixed odd character mod r with q,r≥3 and (r,q)=1.
