Abstract: Finitely generated admissible modules over "vertex algebras of CohFT-type" can be used to construct vector bundles of coinvariants and conformal blocks on moduli spaces of stable curves. In this talk I will say what vertex algebras of CohFT-type are, and explain how such bundles define semisimple cohomological field theories.
As an application, one can give an expression for their total Chern character in terms of the fusion rules. I'll give some examples.
