Given a manifold equipped with a free, properly discontinuous, cocompact ℤ-action, and a flow
on
which is ℤ-equivariant, we study the qualitative dynamics of
. Under certain hypotheses on
, we show that the chain recurrent set of
has a decomposition which is the analogue, in the category of ℤ-equivariant flows, of Smale's spectral decomposition for recurrent sets of Axiom A flows.
