Abstract
Holographic correlators are the basic observables for exploiting and exploring the AdS/CFT correspondence. But the efficient computation of these objects had been a notoriously difficult problem for a long time only until recently. In these three lectures, I will give a brief introduction to the modern methods for computing holographic correlators.
In Lecture 1, I will review the basics which include properties of Witten diagrams and the Mellin representation.
In Lecture 2, I will introduce several complementary bootstrap methods to compute holographic correlators at tree level.
In Lecture 3, I will explain how one can use an AdS analogue of the flat-space unitarity method to compute loop level correlators from tree level input.
