Huisgen-Zimmermann's Grassmannian Parametrization of Representations
(after Huisgen-Zimmermann)

ABSTRACT: I will follow Huisgen-Zimmermann's work to talk about a projective scheme paramerizing representations of a finite dimensional algebra. I will concentrate on its scheme structure, behavior under functors between module categories, and relations to the classical representation varieties. This scheme is endowed with a group action. The invariant theory of this group action will also be discussed.
