On parabolic external maps

Dynamical Systems 2017-11-17 v2

Abstract

We prove that any C1+BVC^{1+BV} degree d2d \geq 2 circle covering hh having all periodic orbits weakly expanding, is conjugate in the same smoothness class to a metrically expanding map. We use this to connect the space of parabolic external maps (coming from the theory of parabolic-like maps) to metrically expanding circle coverings.
