Title:
Self duality defects from holography.

Speaker:
Christian Copetti

Abstract:
We explain how non invertible duality (and more generally n-ality) defects may emerge for theories with a dual holographic description. The key observation is that, at the self duality point, a discrete gauge field emerges in the bulk. We discuss its action through the example of N=4 SYM and develop a formalism to describe the fusion of the ensuing non-invertible defects. Time permitting we mention generalizations to theories of class S.
