Abstract. Given an action of a reductive group on a normal variety, we con-struct all invariant open subsets admitting a good quotient with a quasipro-jective or a divisorial quotient space. Our approach extends known construc-tions like Mumford’s Geometric Invariant Theory. We obtain several new Hilbert-Mumford type theorems, and we extend a projectivity criterion of Bialynicki-Birula and Świȩcicka for varieties with semisimple group action from the smooth to the singular case. 1
