Zbl 0665.58024

This paper is the continuation of part I [see the preceding article]. Let \({\mathcal A}\) be the class of \(C^ 3\)-smooth one dimensional maps f: \(M\to M\) with nondegenerate critical points. Theorem. A map \(f\in {\mathcal A}\) has no wandering intervals.

The theorem is proved by combining the technique of part I with the distortion estimates due to W. de Melo and S. J. van Strien [ibid. 7, 415-462 (1987; Zbl 0609.58023)] (in that paper the absence of wandering intervals for unimodal \(f\in {\mathcal A}\) was established). The main new point is the analysis of intersection multiplicity of intervals in some specific situation.
