Mechanisms of Chaos
- Leonid Bunimovich (Georgia Tech, Atlanta, USA)
Abstract
We discuss mechanisms which generate stochastic behavior in dynamical systems. In systems with impacts (billiards) there are two such mechanisms, dispersing and defocusing. It'll be explained why apparently there are no other such mechanisms, why defocusing is a crucial mechanism in systems with coexistence of chaotic and regular dynamics and why focusing components of the boundary in chaotic billiards should be absolutely focusing.
