Тема: "Holographic correlators finally cracked"
 
Аннотация:
 
In this talk I will discuss recent advances in the computation of four-point functions of 1/2 BPS operators in N=4 SYM using AdS/CFT.
These are the simplest dynamical correlation functions and their study goes back to the early days of AdS/CFT research. Not long ago the proposition of a closed formula in Mellin space for the strong-coupling limit of these four-point functions rekindled interest in them, as further results could disprove or corroborate the conjectured formula.
 
I will discuss how one can compute the strong-coupling limit of these correlation functions using the supergravity action through the AdS/CFT correspondence. I will in particular explain how the algorithm was recently improved to allow for the computation of virtually any correlator of 1/2 BPS operators. Moreover, I will explain how to go from these coordinate space results to Mellin space and back.
