Titre  A Novel Expression for an Integrated Correlator (in N = 4 supersymmetric Yang–Mills theory) 
Résumé  This talk will present the exact expression for an integrated correlator of four superconformal primary operators in the stress tensor multiplet of SU(N) N = 4 supersymmetric YangMills, based on the localised partition function of the N = 2∗ theory. I will show that this integrated correlator can be expressed as a strikingly simple twodimensional lattice sum. This is a function of the complex Yang–Mills coupling, and is manifestly invariant under SL(2, Z) (Montonen–Olive) duality. The correlator satisfies a powerful Laplace equation that relates its value for SU(N) to its value for SU(N−1) and SU(N+1). For finite N the correlator reproduces and extends perturbative and nonperturbative N = 4 SYM results. The largeN expansion is holographically related to the SL(2, Z)invariant low energy expansion of the type IIB superstring fourgraviton amplitude in AdS5 × S5. The talk will also describe the extension of of these results to npoint correlators with n > 4 that violate the U(1) bonus symmetry maximally.
