Assume that G is a group acting on a Polish space. Given a subgroup H of G, by a closed H-selection we mean a closed selection on each orbit of H. We investigate measurability properties of closed H-selections with respect to G-invariant measures, extending some classical result.

Abstract
Assume that G is a group acting on a Polish space. Given a subgroup H of G, by a closed H-selection we mean a closed selection on each orbit of H. We investigate measurability properties of closed H-selections with respect to G-invariant measures, extending some classical result.File in questo prodotto:
