Title: Tensor Models, Algebras, and Topological Holography

Abstract: The counting of observables in tensor models has a rich structure which is organised by underlying algebras related to permutations. This structure also organises the correlators of general observables in Gaussian tensor models. For both counting and correlators, these algebras lead to a topological holography based on lattice topological field theories of permutation groups, and generalizing branched covers of surfaces which play a central role in the string theory of large N two-dimensional Yang Mills theory. The talk is based on https://arxiv.org/abs/1307.6490 and https://arxiv.org/abs/1708.03524 .
