Lyon,    December 5-7, 2022

     The class of integrable dynamical systems, i.e., systems having a sufficient number of conservation laws to describe the behavior of orbits, is of special interest. There are many integrable systems in the nature.  Studying of many problems of geometry leads to natural dynamical systems for which it is important to known, whether they are integrable in some sense or not, and whose study gives links to other domains of mathematics. A classical remarkable example of integrable dynamical system coming from geometry is an elliptic billiard. The famous Birkhoff Conjecture (formulated in 1920-ths) states that the only strictly convex bounded planar integrable billiards are ellipses.
      The talks of the mini-conference will present new results on cross-road between many domains of mathematics related to integrable systems: billiards, Riemann and Kählerian geometries, bicycle mathematics...
                                      There will be three minicourses:
