摘要:Dirichlet character plays an important role in number theory. Almost 100 years have passed since the fundamental contribution of G. Polya and I.M. Vinogradov (1918), there were very few substantial progress like D.A. Burgess's work in late 1950s. The past decade has seen many promising changes due to the success of new ideas and tools. In this talk, some old and new results and several open problems in the field of character sums will be presented. Also I will introduce the joint works with Profs. C.H. Jia and M.A. Korolev.
