Deformations of Koszul algebras and a cool duality

SPEAKER: Nicholas Proudfoot

TITLE: Deformations of Koszul algebras and a cool duality

ABSTRACT: I will define a canonical flat deformation of any Koszul algebra, and show that the centers of the deformations of Koszul dual algebras satisfy a mysterious duality between commutative algebras that was first introduced by Goresky and MacPherson.
