Abstract

In 1955, Mark Kac introduced a simple model to study the

evolution of a gas of particles undergoing pairwise collisions. Although

extremely simplified to be rigorously treatable, the model maintains

interesting aspects of gas dynamics. In recent years, we worked to

extend the analysis to more "realistic" versions of the original model.


I will introduce the Kac model and present some standard and more recent

results. These results refer to a system with a fixed number of

particles and at fixed kinetic energy (micro canonical ensemble) or

temperature (canonical ensemble). I will introduce a "Grand Canonical"

version of the Kac system and discuss new results on it.
