Webinar: Quiver varieties and their combinatorial crystal structure

Deniz Kus

Ruhr-University Bochum

The aim of this talk is to describe combinatorially the crystal operators on the geometric realization of crystal bases in terms of irreducible components of quiver varieties. As a consequence of this description one can extend the geometric description to an affine crystal isomorphic to a Kirillov-Reshetikhin crystal. The underlying combinatorics is in terms of Auslander Reiten quivers.
