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 , we first classify vector bun…

Constructing Maximal Cohen-Macaulay Sheaves on Symplectic Singularities
Shang Xu
In this paper, we study maximal Cohen-Macaulay sheaves on symplectic singularities. These sheaves generate the singularity categories and thus measure how far a singularity is from…
