Equivariant Maximal Cohen-Macaulay sheaves on the minimal orbit closures

Shang Xu

In this paper, we study maximal Cohen-Macaulay sheaves on closures of minimal nilpotent orbits in simple Lie algebras. For singularities of type $A_{n}$ , we first classify vector bun…

$g_{0}$ -Geometry and Its Relationship with Stable Representations

Shang Xu

This paper explores the sheaves with the action of a lie algebra and computes their cohomology in a new category. Then in the following sections, We try to generalize a classical r…
