"Modular invariants in strongly-coupled N=4 super-Yang-Mills"

Abstract:In this talk, I will first review some of the recent progress 
on computing holographic correlators using analytic bootstrap techniques 
combined with supersymmetric localization, focusing on the case of the N 
= 4 super-Yang-Mills theory. From taking a certain flat space limit of 
the holographic correlators, one can obtain scattering amplitudes of 
gravitons in string theory, and one can then reproduce some of the known 
results for these scattering amplitudes. In particular, from instanton 
effects in the N=4 SYM theory, I will explain how to reproduce the 
non-holomorphic Eisenstein series known to appear in type IIB string 
theory scattering amplitudes, and I will explain how to derive many 
other modular invariants appearing in correlation functions of the N=4 
SYM theory.
