Let G a sub-group of the group of homeomorphisms of a metric space E, Homéo(E), such that each orbit of G is finite (the cardinality of orbits is not uniformly limited i.e for all n \in IN there exists x\in E such that card(G(x)) > n (G(x) is the orbit of x by G). A point x in E is regular if there exists an open neighboorhod U_x and an integer k_x such that for all y\in U_x we have card(G(y)) < k_x. if E is connected and G is finitely generated and if each point x \in E is regular is it true that G is finite? In particular we have if E is compact (or each orbit meets a compact K \subset E) then G is finite. cordially.
