We prove that a Morse-Smale gradient-like flow on a closed manifold has a "system of compatible invariant stable foliations"that is analogous to the object introduced by Palis and Smale in their proof of the structural stability of Morse-Smale diffeomorphisms and flows, but with finer regularity and geometric properties. We show how these invariant foliations can be used in order to give a self-contained proof of the well-known but quite delicate theorem stating that the unstable manifolds of a Morse-Smale gradient-like flow on a closed manifold M are the open cells of a CW-decomposition of M.

Abstract
We prove that a Morse-Smale gradient-like flow on a closed manifold has a "system of compatible invariant stable foliations"that is analogous to the object introduced by Palis and Smale in their proof of the structural stability of Morse-Smale diffeomorphisms and flows, but with finer regularity and geometric properties. We show how these invariant foliations can be used in order to give a self-contained proof of the well-known but quite delicate theorem stating that the unstable manifolds of a Morse-Smale gradient-like flow on a closed manifold M are the open cells of a CW-decomposition of M.File in questo prodotto:
