DINAMICI VI - the sixth workshop of the Italian dynamicists

Marked length spectrum and the geometry of open dispersing billiards

speaker: Peter Balint (Budapest University of Technology and Economics)

abstract: We consider open dipersing billiards obtained by removing three strictly convex scatterers satisfying a non-eclipse condition from the plane. We show that information on the length of all periodic orbits determine the Lyapunov exponents and the curvatures of the scatterers at the base points of period two orbits. This is joint work with Jacopo de Simoi, Vadim Kaloshin and Martin Leguil.
