On the shape of attractors of discrete dynamical systems

Abstract

Let MM be a manifold or (more generally) a locally compact, metrizable ANR. If KK is an attractor for a flow in MM, with basin of attraction A(K)\mathcal{A}(K), it is well known that the inclusion i:KA(K)i : K \subseteq \mathcal{A}(K) is always a shape equivalence. In this paper we investigate to what extent this generalizes to discrete dynamical systems generated by homeomorphisms, proving that it holds if (and only if) KK has polyhedral shape. Then we specialize to the case when MM is a manifold of dimension 3\leq 3.
