Description
Abstract: In this talk, we propose a universal expression for the sphere partition function evaluated in hybrid phases of Calabi-Yau GLSMs that are fibrations of Landau-Ginzburg orbifolds over some base manifold. Special cases include Calabi-Yau complete intersections in toric ambient spaces and Landau-Ginzburg orbifolds. We will explain the building blocks entering the expression and test the proposal for
one- and two-parameter Abelian GLSMs, making connections, where possible, to known results from mirror symmetry and FJRW theory. This talk is based on arXiv:2008.03089 with J. Knapp.
