Abstract

In a previous work it is shown that every finite group GG of diffeomorphisms of a connected smooth manifold MM of dimension 2\geq 2 equals, up to quotient by the flow, the centralizer of the group of smooth automorphisms of a GG-invariant complete vector field XX (shortly XX describes GG). Here the foregoing result is extended to show that every finite group of diffeomorphisms of MM is described, within the group of all homeomorphisms of MM, by a vector field. As a consequence, it is proved that a finite group of homeomorphisms of a compact connected topological 44-manifold, whose action is free, is described by a continuous flow.
