DESCRIPTION:Speaker: Peter Balint\nhosted by Kaloshin Group\nAbstract: The 
 planar periodic Lorentz gas describes the motion of a billiard particle in
  a periodic arrangement of convex scatterers. The case of infinite horizon
  -- when the flight time between consecutive collisions is unbounded -- is
  a popular model of anomalous diffusion. For fixed scatterer size\, Sz\\as
 z and Varj\\u proved a limit theorem for the displacement of the particle 
 with a non-standard $\\sqrt{n \\log n}$ scaling. In my talk I would like t
 o describe the asymptotics of this limit law in a setting when as time $n$
  tends to infinity\, the scatterer size may also tend to zero simultaneous
 ly at a sufficiently slow pace. This is joint work with Henk Bruin and Dal
 ia Terhesiu.
