Title: Intersection Spaces and Toric Varieties
Abstract: Toric varieties form a class of possibly singular algebraic varieties that most
geometers are familiar with. Intersection spaces are assigned to certain singular
spaces to restore Poincaré duality and provide a generalized cohomology theory
on singular spaces.
In this talk, I will explain the two concepts and show why it is good to examine
intersection spaces of toric varieties and motivate the combination of the two
concepts both from a theoretical (Poincaré duality) and an application (mirror
symmetry) point of view
