Abstract: | In this Letter, we consider Kontsevich's wheel operators for linear Poisson structures, i.e. on the dual of Lie algebras . We prove that these operators vanish on each invariant polynomial function on *. This gives a characterization of the Kontsevich star products which are deformations relative to the algebra of invariant functions. |
