Finite W-algebras for gl_N
Alberto De Sole, Victor G. Kac, Daniele Valeri
We study the quantum finite W-algebras W(gl_N,f), associated to the Lie algebra gl_N, and its arbitrary nilpotent element f. We construct for such an algebra an r_1 x r_1 matrix L(…

MasterPVA and WAlg: Mathematica packages for Poisson vertex algebras and classical affine -algebras
Matteo Casati, Daniele Valeri
We give an introduction to the Mathematica packages "MasterPVA" and "MasterPVAmulti used to compute lambda-brackets in Poisson vertex algebras, which play an important role in the…
