Title:
Interplay between ribbon graphs and CohFT
Speaker:
Abstract:
We will review an axiomatic formulation of a 2D TQFT whose formalism is based on the edge-contraction operations on graphs drawn on a Riemann surface (cellular graphs). We will describe a new result, that ribbon graphs provide both cohomological field theory and a visual explanation of Frobenius-Hopf duality. This is based on work in progress with Motohico Mulase.
