Dispersing billiards with moving scatterers

fisica matematica

We propose a model of Sinai billiards with moving scatterers, in which the locations of the scatterers are shifted by a small amount after each collision. In order to analyze the model we construct a coupling for non-stationary compositions of dispersing billiard maps and demonstrate exponential loss of memory for the system.
