Title:
Coproduct for Affine W-algebras
Abstract :
The W-algebras are vertex algebras defined by the generalized Drinfeld-Sokolov reductions. Using the Wakimoto representations of affine Lie algebras, we describe the explicit formulae of the screening operators for the W-algebras with generic level. As applications, we show that the W-algebras of type A have the “coproduct” structures
