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.
