RESUMO

We study a two parameter family of billiards in circular tables with an internal obstacle. The dynamic is described by the action of an homeomorphism of the compact cylinder. We study the stability of the xed points and we use the symmetries of the problem to analyze the behavior of the invariant manifolds of the hyperbolic xed point. We prove the existence of homoclinic points for some parameters and we study the dynamical implication of the homoclinic intersection with topological crossing.
