A generalized Harish-Chandra isomorphism
arXiv:0912.1100 · doi:10.1016/j.aim.2010.08.001
Abstract
For any complex reductive Lie algebra g and any locally finite g-module V, we extend to the tensor product of U(g) with V the Harish-Chandra description of g-invariants in the universal enveloping algebra U(g).
