Intersections of twisted cotangent bundles and symplectic duality
Naichung Conan Leung, Yunsong Wei
We observe that numerous symplectic resolutions can be expressed as intersections of twisted cotangent bundles. Additionally, their dual symplectic resolutions can be derived from…

Invariant algebraic D-modules over affine algebraic groups
Yunsong Wei
We study the invariant algebraic D-modules on an affine variety under the action of an algebraic group.For linear algebraic groups with the multiplication action by themselves, suc…

Diagonal orbits in the wonderful compactification
Yunsong Wei
The various types of compactifications of symmetric spaces and locally symmetric spaces are well-studied. Among them, the De Concini-Procesi compactification, also known as the won…
