Description:

A cluster algebra is a kind of commutative algebra with a distinguished set of generators organized into overlapping finite subsets called clusters. Though the definition of a cluster algebra seems strange at first encounter, these algebras appear naturally in many areas of mathematics. In the two decades since they were first discovered, cluster algebras have been used to study topics as seemingly different as Grassmannians, Teichmüller spaces, and the representation theory of finite-dimensional algebras. This course will give an introduction to cluster algebras, focusing on examples from several different areas of mathematics.


Prerequisite:

Basic algebra and topology

    Abstract:In the first part of this talk, I will briefly introduce categorification of acyclic quantum cluster algebras by cluster categories of acyclic quivers, based on the work of Fan Qin. In the second part, I will explain how to categorify certain quantum cluster algebras using cluster categories of coherent sheaves on weighted projective lines. Concretely, we firstly define specialized qu...
