Abstract
In a previous work it is shown that every finite group of diffeomorphisms of a connected smooth manifold of dimension equals, up to quotient by the flow, the centralizer of the group of smooth automorphisms of a -invariant complete vector field (shortly describes ). Here the foregoing result is extended to show that every finite group of diffeomorphisms of is described, within the group of all homeomorphisms of , by a vector field. As a consequence, it is proved that a finite group of homeomorphisms of a compact connected topological -manifold, whose action is free, is described by a continuous flow.
