Robust degenerate unfoldings of cycles and tangencies

Dynamical Systems 2021-02-12 v2

Abstract

We construct open sets of degenerate unfoldings of heterodimensional cycles of any co-index c>0c>0 and homoclinic tangencies of arbitrary codimension c>0c>0. These sets are known to be the support of unexpected phenomena in families of diffeomorphisms, such as the Kolmogorov typical co-existence of infinitely many attractors. As a prerequisite we also construct robust homoclinic tangencies of large codimension which cannot be inside a strong partially hyperbolic set.
