#### The Geometry of Type A Quiver Representations

###### Anna Weigandt (UIUC Math )

Abstract: A quiver is a finite directed graph. We will look at quiver representations, an assignment of a vector space to each vertex and a linear map to each arrow. A natural question is to study isomorphism classes of quiver representations. Equivalently, we may look at orbits of a group action on some associated affine space. Taking orbit closures, we obtain varieties called quiver loci. We will discuss the Zelevinsky map, which realizes each equioriented type A quiver locus as an open affine piece of a Schubert variety.
