Let X be a recurrent point of a planar system, that is, there is a sequence tn →±[infinity] such that φtn (X) → X. (a) Prove that either X is an equilibrium or X lies on a closed orbit. (b) Show by example that there can be a recurrent point for a nonplanar system that is not an equilibrium and does not lie on a closed orbit.
