Description
The giant graviton expansion reorganizes finite-N indices in superconformal field theories as the large-N answer corrected by a systematic series of finite-N contributions. These corrections admit a natural holographic interpretation in terms of branes in the bulk, known as giant gravitons. I will discuss the derivation of this expansion for the half-BPS index of N=4 SYM directly from AdS5 × S5, and explain how the analytic continuation appearing in previous formulations is naturally understood as wall-crossing.
