Classical and super W-algebras from a zero-curvature condition

Abstract
Starting from superdifferential operators in an superfield formulation, we present a systematic prescription for the derivation of classical and super W-algebras by imposing a zero-curvature condition on the connection of the corresponding first order system. We illustrate the procedure on the first non-trivial example (beyond the superconformal algebra) and also comment on the relation with the Gelfand-Dickey construction of -algebras.
