LetGbe a simple algebraic group overand letPbe a parabolic subgroup ofGwith commutative unipotent radicalN+≠ {1}. To each non-openP-orbitCon Lie(N+) we construct an action of Lie(G) on the coordinate algebraof the closureofC. This is a natural generalization of Goncharov’s result dealing with the case whereCis the orbit of the highest root vector. It is also shown thatis an irreducible highest weight module.
