Organized by: Dzmitry Dudko, Mikhail Lyubich and Konstantin Khanin

The goal of this Workshop is to explore connections between various
aspects of Renormalization in Dynamics (unimodal and circle, holomorphic and cocyclic, Henon, KAM, and stochastic renormalizations) and Physics (QFT and statistical mechanics, fluid dynamics, and KPZ), which could help to reveal a unifying theme for all these phenomena.

This workshop is part of the Program: Renormalization and universality in Conformal Geometry, Dynamics, Random Processes, and Field Theory. There will also be Renormalization retrospective: Feigenbaum Memorial Conference held right before.
