A result in global bifurcation theory using the Conley index
We study a saddle-node bifurcation in a Lipschitz family of
diffeomorphisms on a manifold, in the
case that the stable set and unstable set of the fixed point intersect transversally
in a countable collection of one-dimensional manifolds diffeomorphic to circles.
We formulate generic conditions on the circles stated in terms of
standard coordinates, a recently defined tool for the study of saddle-node
bifurcations. Under the conditions, it is shown that there is a
decreasing sequence of intervals $[\underline{\mu_j},\overline{\mu_j}]$ of parameter values for which the
diffeomorphism is semi-conjugated to shift dynamics on the space of binary sequences.
The semi-conjugacy is implied by a recent result in the Conley index theory.
