The specific four-point functions we consider are integra ted correlators obtained by taking various combinations of four derivative s of m\, b\, and tau of the sphere free energy deformed by mass m and squa shing parameter b\, which can be computed using supersymmetric localizatio n. We show that at each order in 1/N\, these quantities can be written in terms of modular invariants\, such as the well studied non-Holomorphic Eis enstein series as well as some new generalizations thereof. These results reproduce known features of the low-energy expansion of the four-graviton amplitude in type IIB superstring theory in ten-dimensional flat space\, w hich is the first check of AdS/CFT at finite string coupling\, and have in teresting implications for the structure of the analogous expansion in AdS _5 × S^5.\n LOCATION:https://researchseminars.org/talk/CCTP_HEP/18/ END:VEVENT END:VCALENDAR
