Twisted Yangians and finite W-algebras

SPEAKER: Jonathan Brown

TITLE: Twisted Yangians and finite W-algebras

ABSTRACT: We construct an explicit set of generators for the finite W-algebras associated to nilpotent matrices
in the symplectic or orthogonal Lie algebras whose Jordan blocks are all of the same size.
We use these generators to show that such finite W-algebras are quotients of twisted Yangians.
