Let a reductive group G act on an algebraic variety X. We give a Hilbert-Mumford type criterion for the construction of open G-invariant subsets V⊂X admitting a good quotient by G.

Soit X une variété algébrique munie d’une action d’un groupe réductif G. On donne un critère à la Hilbert-Mumford pour la construction des ouverts G-stables V⊂X admettant un bon quotient par g.
