报告摘要：

In this talk, we study the integrated correlators in four dimensional N = 4 super Yang-Mills theory, which contain rich physics such as scattering amplitude in AdS5 and supersymmetric partition function on four sphere and have interesting mathematical structures. After reviewing some known results about integrated four-point correlators, I will talk about the integrated two-point correlators in the presence of a line operator, which are still largely unexplored. In particular, we analyze their modular property under SL(2,Z) action and (conjecturally) decompose them into a new class of automorphic forms. This is based on some work in progress with Daniele Dorigoni, Michael Green, Daniele Pavarini, Congkao Wen and Haitian Xie.
