A new deformation of W-infinity and applications to the two-loop WZNW and conformal affine Toda models

Technical Report:

Abstract

We constructed a center less W-infinity type of algebra in terms of a generator of a center less Virasoro algebra and an Abelian spin-1 current. This algebra conventionally emerges in the study of pseudo-differential operators on a circle or alternatively within KP hierarchy with Watanabe`s bracket. Construction used here is based on a special deformation of the algebra w{sub {infinity}} of area preserving diffeomorphisms of a 2-manifold. We show that this deformation technique applies to the two-loop WZNW and conformal affine Toda models, establishing henceforth W {infinity} invariance of these models. (author).
