\(C^ 2\)-endomorphisms of the circle; Block and Franke's theorem; periodic points
In this paper we give an extension to \(C^ 2\)-endomorphisms of the circle of the well known Denjoy's theorem on \(C^ 2\)-diffeomorphisms. We also give a simple proof of an extension of Block and Franke's theorem on the existence of periodic points for maps of the circle.
