Abstract

In Conley index theory one may study an invariant set SS by decomposing it into an attractor AA, a repeller RR, and the orbits connecting the two. The Conley indices of SS, AA and RR fit into an exact sequence where a certain connection homomorphism Γ\Gamma plays an important role. In this paper we provide a dynamical interpretation of this map. Roughly, RR "emits" an element of its Conley index as a "wavefront", part of which intersects the connecting orbits in SS. This subset of the wavefront evolves towards AA and is then "received" by it to produce an element in its Conley index.
