Large N BPS Correlators, Branes, and Semiclassics |

Résumé |
I will discuss recent progress in understanding correlation functions of heavy
protected operators in N=4 SYM in the large N limit. First I will present a
general formalism for computing protected three point functions for operators
whose dimensions scale with the number of colors N_c. Along the way I will
demonstrate how to reconstruct explicit half-BPS operators dual to any given
asymptotically AdS half-BPS background of type IIB supergravity and comment on the
analogous problem for operators preserving fewer supersymmetries. Then I will
revisit the holographic calculation of three point functions of giant gravitons
and single trace operators, pointing out inconsistencies in previous approaches. I
will then propose a resolution to the apparent disagreement between supergravity
and gauge theory in the computation of extremal correlators involving heavy
probes. |
