讲座题目1：Bounds on bilinear sums Kloosterman sums
讲座时间：15:00
讲座内容简介：
In this talk we shall discuss some elementary arguments to obtain new bounds on bilinear sums with weighted Kloosterman sums which complements those recently obtained by E. Kowalski, P Michel and W. Sawin (2020) and shall discuss its possible applications to get average values of divisor functions over families of arithmetic progressions.
讲座题目2：Higher order moments of generalised quadratic Gauss sums weighted byL-functions.
讲座时间：16:50
讲座内容简介：The main purpose of this talk is to study higher order moments of the generalized quadratic Gauss sums weighted by L-functions using estimates for character sums and analytic methods. We find asymptotic formulas for a few character sums which arise naturally in the study of higher order moments. We then use these character sum estimates to deduce asymptotic formula for the higher order moments of the generalized quadratic Gauss sums weighted by L-functions.
