Decay of geometry for Fibonacci critical covering maps of the circle
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2009)
We study the growth of Df `` (f(c)) when f is a Fibonacci critical covering map of the circle with negative Schwarzian derivative, degree d >= 2 and critical point c of order l > 1. As an application we prove that f exhibits ...
Rigidity for piecewise smooth homeomorphisms on the circle
(ElsevierAcademic PressSan Diego, 2014-01-15)
We find conditions for two piecewise 'C POT.2+V' homeomorphisms f and g of the circle to be 'C POT.1' conjugate. Besides the restrictions on the combinatorics of the maps (we assume that the maps have bounded combinatorics), ...
Renormalization for piecewise smooth homeomorphisms on the circle
(Annales de l'Institut Henri Poincaré (C) Non Linear AnalysisBrasil, 2013)
In this work we study the renormalization operator acting on piecewise smooth homeomorphisms on the circle, that turns out to be essentially the study of Rauzy–Veech renormalizations of generalized interval exchange maps ...
