Feliks Przytycki (IMPAN, Warsaw) Geometric coding trees for iterations of rational maps Abstract: Gct's provide coding of their limit sets, e.g. Julia set or its part such as the boundary of the immediate basin of attraction of an attracting fixed point. They play a role of Riemann maps with their boundary behaviour. They help to study Gibbs and harmonic measures ws Hausdorff ones. I will remind some my results on it from eighties (joint with M. Urbański and A. Zdunik) and some more recent observations and questions. I will follow last sections of my ICM'18 talk.
