Maths HEP Lunchtime Seminars: Topological AdS/CFT

Presented by Paul Richmond, King's College London

11 October 2019 13:00 in CM101

I will describe recent work to define holographic duals to topologically twisted supersymmetric gauge theories on Riemannian three-manifolds and four-manifolds. In particular I'll show that the bulk holographically renormalised supergravity actions are independent of the boundary metrics as required for a topological theory. By analysing the geometry of supersymmetric bulk solutions the renormalised supergravity actions for smooth fillings can be evaluated. I will also comment on the implications of these results for the large N limits of topologically twisted ABJM and N = 4 SYM.
