Abstract

In a series of recent works, the supervisor and colleagues found evidence that non-ergodicity of a chaotic Hamiltonian system universally leads to entropy growth and, consequently, the exponential growth of energy during a periodic oscillation parameters. In this project, we aim at building a rigorous mathematical theory to describe this phenomenon. This is an important step towards understanding the dynamics Hamiltonian. We will replace the theorem of Anosov-Kasuga by a general principle of averages that applies to any Hamiltonian system, not only the ergodic. (AU)
