Polynomial Estimates and Discrete Saddle-node Homoclinic Orbits


We derive polynomial rates of convergence for obits of maps that converge to an equilibrium via the center manifold. Similar estimates are obtained for the variational equation along these orbits. We show how these results apply to the analysis of discrete saddle-node homoclinics.
