We study Duffing-like equations of the type q = q-alpha(t)W' (q), with alpha is an element of C( R, R) periodic. We prove that if the stable and unstable manifolds to the origin do not coincide, then the system exhibits positive topological entropy.

Abstract
We study Duffing-like equations of the type q = q-alpha(t)W' (q), with alpha is an element of C( R, R) periodic. We prove that if the stable and unstable manifolds to the origin do not coincide, then the system exhibits positive topological entropy.File in questo prodotto:
