On parabolic external maps
arXiv:1603.01609 · doi:10.3934/dcds.2017220
Abstract
We prove that any degree circle covering 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.
