Propriedades genéricas das classes homoclínicas

Abstract

We consider the vector fields C1 on a compact Riemannian manifold, boundaryless of finite dimension n, with n ≥3. A homoclinic class of a vector field is the closure of the set transverse homoclinic point associated with a hyperbolic periodic orbit. In this work, we prove that the homoclinic classes for a residual set of vector fields C1, are neutral sets, moreover, the homoclinic class is the intersection of the closure the stable set and unstable set. As a consequence of the properties of the neutral sets, we prove the generic properties of homoclinic classes. Thus, we proved that in the homoclinic classes of generic C1 vector fields X are maximal transitive sets, saturated and depend continuously on the periodic orbit. We also proved that a homoclinic class X, does not exhibit cycles of X formed by homoclinic class of X. Furthermore, homoclinic class X is isolated if it only if it is Ω-isolated. But still, it is isolated, the homoclinic class is hyperbolic. All these properties are well known to structurally stable vector fields and Axiom A.
