SUMMARY:Joffrey Mathien (I2M\, AMU\, CNRS): Probabilistic mixing for the ge
 odesic flow on hyperbolic varieties
DESCRIPTION:Joffrey Mathien: For an ergodic dynamical system\, the cutoff d
 escribes an abrupt transition to equilibrium. Historically introduced by D
 iaconis\, Shahshahani and Aldous for card shuffling and other random walks
  on finite groups\, there are now numerous examples of Markov chains and M
 arkov processes where the cutoff has been established.\n\nIn this talk\, w
 e try to introduce progressively and study cutoff for geodesic paths on co
 mpact hyperbolic manifolds\, and we develop a spectral strategy introduced
  by Lubetzky and Peres in 2016 for Ramanujan graphs and further developed 
 in different geometric contexts. (j.w. with C. Bordenave).
