SUMMARY:Serge Troubetzkoy (I2M\, Aix-Marseille Université): Interval trans
 lation maps and billiards with spy mirrors
DESCRIPTION:Serge Troubetzkoy: A not necessarily piecewise isometry of the 
 interval is called an interval translation map\; the well known invertible
  case is known as an interval exchange. Interval translation maps arise as
  first return maps in rational polygonal billiards with spy mirrors.\nI wi
 ll speak on recent results with Sasha Skripchenko on the topological entro
 py and complexity of polygonal billiards with spy mirrors.\n\n\n
