Abstract/Résumé:

We develop a renormalization theory for analytic homeomorphisms of the circle with two cubic critical points. We prove a renormalization hyperbolicity theorem. As a basis for the proofs, we develop complex a priori bounds for multi-critical circle maps.

On développe une théorie de renormalisation pour les homéomorphismes analytiques du cercle à deux points critiques cubiques. On démontre un théorème d’hyperbolicité dans le cadre de renormalisation. Comme base des démonstrations, on développe des bornes complexes a priori pour les applications du cercle dans lui-même aux points critiques multiples
