Title Making AdS_3 x S^3 more like AdS_5 x S^5
Abstract Holographic CFTs possess a certain point in moduli space where there is a weakly coupled gravity dual. Computing the first non-trivial term in a four-point function using this description used to involve tedious work but much of this has now been superseded by bootstrap methods. In the case of AdS_5 x S^5 supergravity, there are now compact expressions for infinitely many tree-level four-point functions and these have served as a stepping stone towards correlators with loops, stringy corrections and more external legs. AdS_3 x S^3 is another supergravity background with a close connection to known holographic CFTs but it has not yet been put on the same footing. In this talk, I will explain why the obstacles are less daunting than they used to be and how they can be overcome with a formalism based on multiple Mellin amplitudes.
