QM Research Seminar: Ricci flat metrics from GLSM with a shadow, and generalized CY ansatz

Speaker: Ondrej Hulik (Heidelberg University).

Abstract: 
GLSM models describe a large class of interesting geometries as symplectic quotients. However, they generally cannot produce a Ricci-flat metric on the quotient space. I will present a new construction/extension of standard GLSM techniques that circumvents this problem. Furthermore, using toric geometry, I will explain how this method is related to the Calabi–Yau ansatz known in the literature.
