Rigidity of $C^2$ Infinitely Renormalizable Unimodal Maps
Given $C^2$ infinitely renormalizable unimodal maps $f$ and $g$ with a quadratic critical point and the same bounded combinatorial type, we prove that they are $C^{1+α}$ conjugate along the closure of the corresponding forward orbits of the critical points, for some $α>0$.
