DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CGP-MP/28/">
 The B-model for singular spectral curves and its enumerative interpretatio
 n</a>\nby Gaëtan Borot (Institute for Mathematics & Institute for Physics
 \, Humboldt University of Berlin) as part of IBS-CGP Mathematical Physics 
 Seminar\n\n\nAbstract\nI will discuss the definition of B-model/topologica
 l recursion for spectral curves and explain the obstructions to the well-p
 osedness of this definition for arbitrary spectral curves. The question ca
 n be approached by the representation theory of W-algebras\, and I will de
 scribe the largest known class of admissible spectral curves (including si
 ngular 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 par
 ticular l will describe possible applications in open r-spin intersection 
 theory.\n
