DESCRIPTION:A longstanding problem in holography is the reconstruction of 
 the entropy of black holes via a field theory calculation. Recently\, much
  progress has been made in the context of supersymmetric black holes in Ad
 S_5 and the superconformal index of N=4 SU(N) Super Yang-Mills.\n\nIn a so
 on to be published work with Ofer Aharony\, Francesco Benini\, and Paolo M
 ilan we analyze the index in the Bethe Ansatz approach\, expressing it as 
 a sum. We then find that in the large N limit each term in the sum can be 
 identified with the contribution of a different (complex) supersymmetric b
 lack hole solution\, and reproduce some of its perturbative and non-pertur
 bative contribution. The non-perturbative terms introduce a stability cond
 ition that explains why certain bulk solutions satisfy the same boundary c
 onditions\, but do not appear in the index. Finally\, we argue for an exac
 t match between the sets of solutions on both sides.\n
