Dear all, Next week, Friday March 13, Ian Melbourne (University of Warwick) will give a talk at USyd in Carslaw 157 at 11am on Title: Anomalous diffusion in deterministic systems. Part II Abstract: Part (i) of the old abstract (below) was covered in the first talk. In this talk, I’ll focus on part (ii). Exact fast-slow systems were covered by a paper with Gottwald in 2013. The general case requires extra control in p-variation and is treated in work with Chevyrev, Friz & Korepanov. (The situation regarding Skorohod topologies gets even worse / more interesting than in the first talk, but I’ll keep it as nontechnical as possible.) Old Abstract: In sufficiently slowly mixing dynamical systems, the classical central limit theorem breaks down and may lead to convergence to a superdiffusive Levy process. After reviewing older work on Pomeau-Manneville intermittent maps, I will describe recent results on (i) convergence to Levy processes in billiards, (ii) convergence to superdiffusive stochastic processes in fast-slow systems. Hope to see you all there, Lachlan
