Abstract: (Springer)
We provide general formulae for the topologically twisted index of a general three-dimensional ≥ 2 gauge theory with an M-theory or massive type IIA dual in the large N limit. The index is defined as the supersymmetric path integral of the theory on S × S in the presence of background magnetic fluxes for the R- and global symmetries and it is conjectured to reproduce the entropy of magnetically charged static BPS AdS black holes. For a class of theories with an M-theory dual, we show that the logarithm of the index scales indeed as N (and N in the massive type IIA case). We find an intriguing relation with the (apparently unrelated) large N limit of the partition function on S. We also provide a universal formula for extracting the index from the large N partition function on S and its derivatives and point out its analogy with the attractor mechanism for AdS black holes.Note:
