Speaker: Michele Gianfelice  (Università della Calabria, Italy) Title: Stochastic stability of classical Lorenz flow under impulsive type forcing Abstract: Inspired by the problem of modeling the so called anthropogenic forcing in climatology, e.g. the effects of the emissions of greenhouse gases in the atmosphere, we introduce a novel type of random perturbation for the classical Lorenz flow and … Continue reading Michele Gianfelice (Università della Calabria, Italy) →

Speaker: Gary Froyland (University of New South Wales, Australia) Title: The dynamic ocean Abstract: The circulation of our oceans strongly influences climate, weather and biology. Our ocean currents are dynamic, and fluctuate to varying extents. I will introduce data-driven numerical tools that can tease apart dynamic components of the ocean, with information sourced from ocean … Continue reading Gary Froyland (University of New South Wales, Australia) →

Speaker: Misha Bialy  (Tel Aviv University, Israel) Title: Birkhoff-Poritsky conjecture for centrally-symmetric billiards Abstract: In this talk I shall discuss Birkhoff-Poritsky conjecture for centrally-symmetric C^2-smooth convex planar billiards. We assume that the domain A between the invariant curve of 4-periodic orbits and the boundary of the phase cylinder is foliated by C^0-invariant curves. Under this … Continue reading Misha Bialy (Tel Aviv University, Israel) →
