Title:Time of instability for near-integrable Hamiltonian systems
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Abed Bounemoura, Instituto Nacional de Matemática Pura e Aplicada, Brasil
In this talk, we shall be concerned with certain quantitative aspects on a weak form of instability for near-integrable Hamiltonian systems (known as Arnold diffusion). Using Iterated Function Systems, we shall explain a new construction with an optimal time of instability in the "a priori unstable" case, which should be useful to tackle the corresponding problem in the much more difficult "a priori stable" case.
