Title	Black hole states at finite N
Abstract	We study novel cohomologies for the local BPS operators of the maximal super-Yang-Mills theory to better understand the black hole microstates. We first analyze the index of these black hole operators and explicitly construct their cohomologies, investigating how they capture features of quantum black holes. We find many towers of states and partial no-hair behaviors, in which certain gravtions are forbidden to dress these black hole operators. We then discuss the qualitative agreement of our results with the behavior of hairy black holes in AdS, so-called grey galaxies and dual dressed black holes.
