Algebra of Screening Operators for the Deformed W n Algebra
We construct a family of intertwining operators (screening operators) between various Fock space modules over the deformed W n algebra. They are given as integrals involving a product of screening currents and elliptic theta functions. We derive a set of quadratic relations among the screening operators, and use them to construct a Felder-type complex in the case of the deformed W 3 algebra.
