DESCRIPTION:Recent studies showed that the N=4 superconformal index leads
to the microstate counting of the BPS black holes in AdS_5 X S^5. I will e
xplain how we can enhance such an account of the AdS black hole entropy fr
om the saddle point analysis of the matrix model for the N=4 index. Firstl
y\, I will focus on the small black holes whose sizes are much smaller tha
n the AdS radius. The saddle point equation can be solved exactly in this
limit. The exact free energy obtained in this way gives a first principle
account for the counting of the asymptotically flat black holes. Secondly\
, motivated by the previous exact solution for the small black holes\, I w
ill explain the saddle point equation can in fact be solved without taking
any limit. I will show the saddles corresponding to the known BPS black h
oles arise as 'areal' distributions. The talk is based on https://arxiv.or
