Counting Tensor Model Observables and Branched Covers of the 2-Sphere
(2014-02-04)
Lattice gauge theories of permutation groups with a simple topological action (henceforth permutation-TFTs) have recently found several applications in the combinatorics of quantum field theories (QFTs). They have been ...
Interactions as intertwiners in 4D QFT
In a recent paper we showed that the correlators of free scalar field theory in four dimensions can be constructed from a two dimensional topological field theory based on so(4,2) equivariant maps (intertwiners). The free ...
