The subconvexity problem
Estimating the size of L-functions inside the critical strip is a central problem in the analytic theory of numbers. This problem has a long history originating in the works of Lindelf around 1908. Subconvex estimates often have deep implications. In this talk, the speaker will briefly describe the salient features of this important problem
