Title: Two Gauged Linear Sigma Models for non-spherical Calabi-Yau manifolds
Date: July 13, 2017, 16:00 - 17:00
Place: CERN
Abstract:
I will describe two GLSMs with gauge group U(2), that help to understand geometry of a hyper-kähler 4-fold and of an abelian surface (varieties of lines on del Pezzo manifolds). By RG flow one can relate sigma-models on these CYs to "symmetric squares" of smaller theories, despite the fact that for very general cubic fourfold its variety of lines is not birational to a Hilbert scheme of a K3 surface.
