Abstract

In this letter we study the non-trivial formal differentiable deformations of the Lie algebraN=C (W, IR) whereW is a symplectic manifold. Under some assumptions (satisfied in particular forW=IR2n) we show that these deformations are all equivalent, up to a monomial change of the parameter, to one of them (Moyal for IR2n). Furthermore, if there exists a differentiable *-product corresponding to one of them, each of them is induced by a *-product which is essentially unique.
