Renormalization in the Golden-Mean Semi-Siegel Hénon Family: Universality and Non-Rigidity (1707.04997v2)
Published 17 Jul 2017 in math.DS
Abstract: It was recently shown by Gaidashev and Yampolsky that appropriately defined renormalizations of a sufficiently dissipative golden-mean semi-Siegel H\'enon map converge super-exponentially fast to a one-dimensional renormalization fixed point. In this paper, we show that the asymptotic two-dimensional form of these renormalizations is universal, and is parameterized by the average Jacobian. This is similar to the limit behavior of period-doubling renormalization in the H\'enon family considered by de Carvalho, Lyubich and Martens. As an application of our result, we prove that the boundary of the golden-mean Siegel disk of a dissipative H\'enon map is non-rigid.
