Title: Nakajima quiver varietites and irreducible components of Springer fibers

Speaker: Mee Seong Affiliation: United States Military Academy and Army Research Laboratory Zoom: Contact Karen Yeats

Abstract:

Springer fibers and Nakajima quiver varieties are amongst the most important objects in geometric representation theory. While Springer fibers can be used to geometrically construct and classify irreducible representations of Weyl groups, Nakajima quiver varieties play a key role in the geometric representation theory of Kac--Moody Lie algebras.
