Algebra Seminar

A categorification of Grassmannian cluster algebras

Xiuping Su (University of Bath)

Friday 30 Oct, 12-1pm, Place: Carslaw 375

Abstract: In this talk I will discuss a twisted group ring constructed from the coordinate ring of the singularity \(x^ky^{n-k}\) and study the category of its Cohen-Macaulay modules. Then I will explain how to use Cohen-Macaulay modules over the completion ring to give an additive categorification of Grassmannian cluster algebras.
