Equidistribution of currents under Anosov group actions

Nguyen-Bac Dang, Michael Kapovich, Mikhail Lyubich +1

We study the behavior of currents on flag-manifolds under actions of Anosov subgroups of complex semisimple Lie groups G. Given a current T of bidimension (k, k) on the full flag-m…

Mirrors of conformal dynamics: Interplay between anti-rational maps, reflection groups, Schwarz reflections, and correspondences

Mikhail Lyubich, Sabyasachi Mukherjee

The goal of this survey is to present intimate interactions between four branches of conformal dynamics: iterations of anti-rational maps, actions of Kleinian reflection groups, dy…

Mating parabolic rational maps with Hecke groups

Shaun Bullett, Luna Lomonaco, Mikhail Lyubich +1

We prove that any degree rational map having a parabolic fixed point of multiplier with a fully invariant and simply connected immediate basin of attraction is mateable wit…

MLC at Feigenbaum points

Dzmitry Dudko, Mikhail Lyubich

We prove a priori bounds for Feigenbaum quadratic polynomials, i.e., infinitely renormalizable polynomials of bounded type. It implies local connectivity of t…

Uniform a priori bounds for neutral renormalization. Variation II: -ql Siegel maps

Dzmitry Dudko, Yusheng Luo, Mikhail Lyubich

We extend uniform pseudo-Siegel bounds for neutral quadratic polynomials to -quadratic-like Siegel maps. In this form, the bounds are compatible with the -quadratic…

David extension of circle homeomorphisms, welding, mating, and removability

Mikhail Lyubich, Sergei Merenkov, Sabyasachi Mukherjee +1

We provide a David extension result for circle homeomorphisms conjugating two dynamical systems such that parabolic periodic points go to parabolic periodic points, but hyperbolic…
