Note on the Algebra of Screening Currents for the Quantum Deformed W-Algebra
Abstract
With slight modifications in the zero modes contributions, the positive and negative screening currents for the quantum deformed W-algebra Wq,p(g) can be put together to form a single algebra which can be regarded as an elliptic deformation of the universal enveloping algebra of g, where g is any classical simply-laced Lie algebra.
