Second moments of Dirichlet -functions weighted by Kloosterman sums
For the general modulo and a general multiplicative character modulo , the upper bound estimate of is a very complex and difficult problem. In most cases, the Weil type bound for is valid, but there are some counterexamples. Although the value distribution of is very complicated, it also exhibits many good distribution properties in some number theory problems. The main purpose of this paper is using the estimate for -th Kloosterman sums and analytic method to study the asymptotic properties...
