A Sinai billiard is a dynamical system obtained by a billiard ball moving in a bounded flat region with concave or flat boundaries. Without external field, such systems are often chaotic. With gravity turned on, part of the phase space can show quasiperiodic behavior.. Sinai Billiard - Wolfram Demonstrations Project biliard sinaia. The simple Sinai billiard table is a flat square with a circular wall located at its center. It was introduced by Yakov G.

This model is sometimes called the Lorentz gas and it is usually seen as the reflection of a ray of light by an arrangement of

The Sinai billiard flow on the two-torus, i.e., the periodic Lorentz gaz, is a continuous flow, but it is not everywhere differentiable. Assuming finite horizon, we relate the equilibrium states of the flow with those of the Sinai billiard map -- which is a discontinuous map. biliard sinaia. Universality in statistical measures of trajectories in classical .. For classical billiards we suggest that a matrix of action or length of trajectories in conjunction with statistical measures, level spacing distribution and spectral rigidity, can be used to distinguish chaotic from integrable systems.
