✦ Synopsis

A deformation of the polynomial algebra S(~) on ~when S(~1)is a free I(~)module (I(ç~)= algebra of invariant polinomials)

. This deformation restricts nicely to a large class of orbits. We also give an example to show that deformations of S(~)restricting to orbits may not always be defined by bidifferential operators.
