Title: The coherent-constructible correspondence for toric varieties
Speaker: David Treumann
Speaker Info: University of Minnesota
Brief Description:
Special Note:

This is a talk on joint work with Bohan Fang, Chiu-Chu Melissa Liu, and Eric Zaslow. It is in some sense a sequel to Bohan's March 10 talk, but I will try to keep it independent. I will discuss a triangle of equivalences we have constructed between a category of equivariant coherent sheaves on a toric variety, a category of polyhedrally-constructible sheaves on a real vector space, and a Fukaya category of Lagrangian branes in a symplectic vector space. Many famous results of toric geometry admit interpretations in terms of this coherent-constructible correspondence, and the connection to the Fukaya category can be seen as a verification -- for toric varieties -- of an equivariant form of Kontsevich's homological mirror symmetry conjectures.
