Equivalence and topological invariance of conditions for non-uniform hyperbolicity in the iteration of rational maps

- F. Przytycki, J. Rivera-Letelier, S. Smirnov
- Mathematics
- 2003

Abstract.We show equivalence of several standard conditions for non-uniform hyperbolicity of complex rational functions, including the Topological Collet-Eckmann condition (TCE), Uniform… Expand

Lyapunov characteristic exponents are nonnegative

- F. Przytycki
- Mathematics
- 1993

We prove that, for an arbitrary rational map f on the Riemann sphere and an arbitrary probability invariant measure on the Julia set, Lyapunov characteristic exponents are nonnegative a.e. In… Expand

- 1 May 1990

AbstractLet be a rational function on the Riemann sphere, φ be a Hölder continuous function on the Julia set denote the Perron-Frobenius-Ruelle operator on the space of continuous functions:… Expand

Conical limit set and Poincaré exponent for iterations of rational functions

- F. Przytycki
- Mathematics
- 26 January 1999

We contribute to the dictionary between action of Kleinian groups and iteration of rational functions on the Riemann sphere. We define the Poincaré exponent δ(f, z) = inf{α ≥ 0 : P(z, α) ≤ 0}, where… Expand

External rays to periodic points

- G. Levin, F. Przytycki
- Mathematics
- 1996

We prove that for every polynomial-like holomorphic mapP, ifaεK (filled-in Julia set) and the componentKaofK containinga is either a point ora is accessible along a continuous curve from the… Expand

PREIMAGE ENTROPY FOR MAPPINGS

- Z. Nitecki, F. Przytycki
- Mathematics
- 1 September 1999

Several entropy-like invariants have been defined for noninvertible maps, based on various ways of measuring the dispersion of preimages and preimage sets in the past. We investigate basic properties… Expand

When do two rational functions have the same Julia set

- G. Levin, F. Przytycki
- Mathematics
- 1997

It is proved that non-exceptional rational functions f and g on the Riemann sphere have the same measure of maximal entropy iff there exist iterates F of f and G of g and natural numbers M, N such… Expand
