Palis's conjecture on Morse–Smale systems and transversal homoclinic orbits

A diffeomorphism ff is a diffeomorphism of a compact manifold. Palis's conjecture. Any diffeomorphism can be CrC^r approximated by a Morse–Smale one or by one exhibiting a transversal homoclinic orbit. This conjecture proposes a fundamental dichotomy between simple Morse–Smale dynamics and dynamics with transversal homoclinic complexity; its status is not specified in the source.
