DESCRIPTION:Speaker: Corentin Fierobe\nhosted by Kaloshin Group\nAbstract: 
 A billiard is a bounded domain in which we study the trajectory of a ray o
 f light obtained after successive reflections on the boundary of the domai
 n viewed as a perfectly reflecting mirror. Reflections are given by the cl
 assical law of optics: angle of incidence = angle of reflection. These dyn
 amical systems are intensively studied\, and many interesting questions ar
 ise. Ivriis conjecture is one of them: it states that given a billiard in 
 a Euclidean space\, the set of its periodic orbits has zero measure. Durin
 g this talk\, we will present another type of billiards introduced by S. T
 abachnikov called projective billiards\, which generalizes different types
  of billiards\, and show how they can be useful to understand questions re
 lated to usual billiards like Ivriis conjecture.
