Abstract
Considering one ξ-piece and using Lemma 11 and its proof, we can transport all the H 10 -index of a simple critical point at infinity∞on that single piece. If this H 10 -index is at least 2, we are able to generate a change in the maximal number of zeros of b on the unstable manifold of x ∞. If an iterate of x ∞is of even index 2k, the homology will then be well defined, as far as x ∞is concerned, at the order 2k.
