Algebra seminar (in cooperation with Topology seminar) Title: Cluster algebras of finite mutation type and extended affine Weyl groupsSpeaker: Pavel Tumarkin (Durham University)Abstract: With (almost) every finite mutation class of quivers we can associate two groups: an extended affine Weyl group of type A or D, and a certain quotient of a Coxeter group which behaves nicely with respect to mu...

It is spanned by isotopy classes of framed links in the thickened surface $S \times (-1,1)$. When the quantum parameter $q$ is speci...
