Title: Maximal Cohen-Macaulay Modules on Symplectic Singularities

Time: 14:30-16:00  July 14, 2026 (Tuesday)

Place: MCM110

Abstract: We construct maximal Cohen-Macaulay sheaves on higher dimensional symplectic singularities using coherent duality on Nakajima quiver varieties. We also study the classification of G-equivariant maximal Cohen–Macaulay sheaves on the minimal nilpotent orbits and establish an equivalent criterion in terms of the characters of the corresponding representations of the stabilizer subgroup.
