Description
Twisted holography relates the 2d chiral algebra subsector of N=4 SYM to the B-model topological string theory on the complex manifold SL(2,C). In this talk, I will present the correspondence between determinant operators and “Giant Graviton” branes. In particular, the large N saddles of determinant correlation functions can be matched with semiclassical D-brane configurations and determinant modifications with brane excitations. I will also discuss twisted holography duals of 4d holomorphic theories and their analogous correspondence.
