Bifurcation and chain recurrence

Abstract

AbstractWe show that there is a residual subset of the set of C1 diffeomorphisms on any compact manifold at which the mapis continuous. As this number is apt to be infinite, we prove a localized version, which allows one to conclude that if f is in this residual set and X is an isolated chain component for f, then(i) there is a neighbourhood U of X which isolates it from the rest of the chain recurrent set of f, and(ii) all g sufficiently C1 close to f have precisely one chain component in U, and these chain components approach X as g approaches f.(ii) is interpreted as a generic non-bifurcation result for this type of invariant set.
