Poisson structures of deformed $W$ -algebras and classical $W$ -algebras

Dong Jun Choi, Uhi Rinn Suh

In this paper, we explain how classical $W$ -algebras can be obtained as limits of $q$ -deformed $W$ -algebras in type $A$ . To this end, we give a detailed examination of the construc…

Generalized finite and affine $W$ -algebras in type $A$

Dong Jun Choi, Alexander Molev, Uhi Rinn Suh

We construct a new family of affine $W$ -algebras $W^{k} (λ, μ)$ parameterized by partitions $λ$ and $μ$ associated with the centralizers of nilpotent elements in $gl_{N}$ . The…
