Singularities and non-hyperbolic manifolds do not coincide

Academic Article

Abstract

  • We consider the billiard flow of elastically colliding hard balls on the flat v-torus (v ≥ 2), and prove that no singularity manifold can even locally coincide with a manifold describing future non-hyperbolicity of the trajectories. As a corollary, we obtain the ergodicity (actually the Bernoulli mixing property) of all such systems, i.e. the verification of the Boltzmann-Sinai ergodic hypothesis. © 2013 IOP Publishing Ltd & London Mathematical Society.
