Gandalf (Pure Maths Student Seminar): Mutation-Infinite Cluster Algebras

Presented by John Lawson, Durham

30 January 2014 15:00 in CM107

Cluster algebras were first introduced by Fomin and Zelevinsky in an effort to provide concrete terms to describe "dual canonical bases" in different settings. Cluster algebras are special in that the final construction of the algebra is rarely interesting, rather it is the process of finding the generators of the algebra which yields fascinating results. Generators are found using an iterative process of mutation on labelled seeds, and I am particularly interested in those mutation classes of infinite size.

Gandalf is the pure maths student seminar. Gandalf stands for the Geometry AND ALgebra Forum. It is run by and for pure postgraduates, but welcomes anyone who is interested in coming along.
