DESCRIPTION:Title: Stochastic billiard in a convex set\n\nAbstract: We cons
 ider the following dynamic: a particle moves at unit speed inside a convex
  set until it hits its boundary. At this time\, the particle is reflected 
 inside the domain according to a random distribution\, not depending on it
 s position and its previous velocity. The pair (location\,velocity) of thi
 s particle is a continuous-time Markov process\, and the successive locati
 ons of hitting points on the boundary are a Markov chain. We are intereste
 d in the speeds of convergence of these two processes towards their invari
 ant measures. We will therefore describe a coupling that gives explicit up
 per bounds for these speeds of convergence\, in some particular cases for 
 the convex in which the stochastic billiard evolve.\n
