A Riemannian homogeneous space $X=G/H$ is said to be commutative if the algebra of $G$-invariant differential operators on $X$ is commutative and weakly commutative if the associated Poisson algebra is commutative. Clearly, the commutativity of $X$ implies its weak commutativity. The converse implication is proved in this paper.
Mots-clés : Lie group, Poisson bracket
Keywords: Lie algebra, universal enveloping algebra, homogeneous space, (weakly) commutative space, symplectic manifold, momentum map.
