I will present some decay of correlations results on skew products which are locally accessible. The results rely on the study of a twisted transfer operator and could be generalized to many other situations. I will also present numerical…

Entropy production in nondegenerate diffusions: the large-time and small-noise limits – Renaud Raquépas (McGill University Montréal and Université Grenoble Alpes)
Entropy production (EP) is a key quantity originating from thermodynamics and statistical physics which quantifies the irreversibility of the time evolution of physical systems. I will start with a general introduction to the different approaches to…
Birkhoff-Poritsky conjecture for centrally-symmetric billiards – Misha Bialy (Tel Aviv University (Israel))
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…
