Abstract : Given a manifold M of dimension at least 4 whose universal covering is homeomorphic to a sphere, the main result states that a compact manifold W is isomorphic to a cylinder M $\times$ [0, 1] if and only if W is homotopy equivalent to this cylinder and the boundary is isomorphic to two copies of M; this holds in the smooth, PL and topological categories. The result yields a classification of smooth, finite group actions on homotopy spheres (in dimensions $\geq 5$ ) with exactly two singular points.
