Inverse Hamiltonian reduction for affine W-algebras in type A
Dylan Butson, Sujay Nair
We give a geometric proof of inverse Hamiltonian reduction for all affine W-algebras in type A at generic level, a certain embedding of the affine W-algebra corresponding to an arb…

Inverse Hamiltonian reduction in type A and generalized slices in the affine Grassmannian
Dylan Butson, Sujay Nair
We give a geometric proof of inverse Hamiltonian reduction for all finite W-algebras in type , a certain embedding of the finite W-algebra corresponding to an arbitrary nilpoten…
