Deformed W-algebras as Symmetries of Generalized Integrable Hierarchies

A unified description of the relationship between the Hamiltonian structure of a large class of integrable hierarchies of equations and W-algebras is discussed. The main result is an explicit formula showing that the former can be understood as a deformation of the latter.

Integrable Systems and W-Algebras

The basic concepts underlying our analysis of {\it W-algebras} as extended symmetries of integrable systems are summarized. The construction starts from the second hamiltonian structure of ``Generalized Drinfel'd-Sokolov'' hierarchies, and its correspondence with the $A_1$-embeddings is established, providing a rather simple and general scheme.
