Undoing toric degenerations: an analogue of Greene-Plesser mirror symmetry for the Grassmannian
Elana Kalashnikov (Harvard University)
Abstract: The most basic construction of mirror symmetry compares the Calabi–Yau hypersurfaces of projective space and projective space quotient a finite group G. There is a natural analogue of this finite group action on the Grassmannian Gr(n, r). In this talk, I'll explain how toric degenerations, blow-ups, variation of GIT and mirror symmetry relate the Calabi–Yau hypersurfaces of Gr(n,r) and Gr(n,r)/G. This is joint work with Tom Coates and Charles Doran.
