The B-model for singular spectral curves and its enumerative interpretation

Abstract: I will discuss the definition of B-model/topological recursion for spectral curves and explain the obstructions to the well-posedness of this definition for arbitrary spectral curves. The question can be approached by the representation theory of W-algebras, and I will describe the largest known class of admissible spectral curves (including singular cases) that has been obtained in this way. Each case is expected to have an enumerative interpretation in a sense that I will specify. In particular l will describe possible applications in open r-spin intersection theory.
