Abstract
We reconsider the relation between classicalW-algebras and deformations of differential operators, emphasizing the consistency with diffeomorphisms. Generators of theW-algebra that arek-differentials are constructed by a systematic procedure. The method extends, following Drinfeld and Sokolov, toW-algebras based on arbitrary simple Lie algebras.
