|Title:||On dependence on the order of the perturbation of the exponentially small splitting of separatrices|
|Seminar:||Center for Dynamics and Geometry Seminars|
|Speaker:||Marcel Guardia, Penn State|
|The exponentially small splitting of separatrices appears naturally in analytic integrable Hamiltonian Systems with a fast periodic perturbation. In this setting Melnikov theory fails, in general, to predict correctly the distance between the invariant manifolds due to the exponential smallness. Moreover, this distance is extremely sensitive on the analyticity properties of the Hamiltonian System. In this talk we will explain how it depends on what was called by T. M. Seara and A. Delshams the order of the perturbation. This is joint work with I. Baldoma, E. Fontich and T. M. Seara.|
