Abstract:
In this paper we study the dynamical properties of general ${C^2}$ maps $f:[0,1] \to [0,1]$ with quadratic critical points (and not necessarily unimodal). We will show that if such maps satisfy the well-known Collet-Eckmann conditions then one has (a) hyperbolicity on the set of periodic points; (b) nonexistence of wandering intervals; (c) sensitivity on initial conditions; and (d) exponential decay of branches (intervals of monotonicity) of ${f^n}$ as $n \to \infty ;$ For these results we will not make any assumptions on the Schwarzian derivative $f$. We will also give an estimate of the return-time of points that start near critical points.References
