Abstract
In this talk, I will discuss some exact results of four-point correlation functions in N=4 super Yang-Mills. I will focus on the correlator involving two determinant operators (often called giant gravitons) and two superconformal primary operators in the stress tensor multiplet, and study the associated integrated correlator by integrating over the spacetime dependence. I will show that the integrated correlator can be reformulated as an infinite sum of protected three-point functions, which leads to exact expressions of the integrated correlator in the planar limit and beyond. The SL(2, Z) completion of the results and the comparison with string theory will be discussed as well.
