On the general trigonometric sums weighted by character sums

摘要

The main purpose of this paper is using the estimates for character sums and the mean value properties of Dirichlet L-function to study the hybrid mean value properties of the general trigonometric sums, which is weighted by the 2kth and first power mean of character sums in . The two sharp asymptotic formulae are derived and some interesting connections between these sums are established.
