Smooth Toric Quiver Varieties

Algebraic Geometry 2022-04-20 v2

Abstract

We study smoothness of toric quiver varieties. When a quiver QQ is defined with the identity dimension vector, the corresponding quiver variety is also a toric variety. So it has both fan representation and quiver representation. We work only on quivers with canonical weight and we classify smooth such toric quiver varieties. We show that a variety corresponding to a quiver with the identity dimension vector and the canonical weight is smooth if and only if it is a product of projective spaces or their blowups.
