The C 1 closing lemma for generic C 1 endomorphisms
Annales de l'I.H.P. Analyse non linéaire, Tome 27 (2010) no. 6, pp. 1461-1469

Given a compact m-dimensional manifold M and 1⩽r⩽∞, consider the space C r (M) of self mappings of M. We prove here that for every map f in a residual subset of C 1 (M), the C 1 closing lemma holds. In particular, it follows that the set of periodic points is dense in the nonwandering set of a generic C 1 map. The proof is based on a geometric result asserting that for generic C r maps the future orbit of every point in M visits the critical set at most m times.
