Density of hyperbolicity and homoclinic bifurcations for attracting topologically hyperbolic sets
Enrique R. Pujals
Keywords:
Given a topologically hyperbolic attracting set of a smooth three dimensional Kupka-Smale diffeomorphism, it is proved under some hypothesis over the dissipation rate, that the set is either hyperbolic or the diffeomorphisms is $C^1-$ approximated by another one exhibiting either a heterodimensional cycle or a homoclinic tangency.
