Bea Schumann (Köln), Nakajima quiver varieties and combinatorics of
We give a gentle introduction to Nakajima quiver varieties,
certain projective varieties attached to quivers, motivated by questions in
Lie theory. We then explain how combinatorics of Auslander-Reiten quivers of
Dynkin quivers may be used to understand their irreducible components and
the associated crystal structures in the finite type case. This talk is
based on joint work with Deniz Kus.
