Abstract
We consider the dynamical system ( {Mathematical expression}, μ, Tt) where ( {Mathematical expression}, μ) is the Gibbs ensemble at some fixed temperature and density for a semi-infinite one-dimensional ideal gas of point particles. The first particle has mass M, all the other particles mass m<M. Tt is the time evolution which describes free motion of the particles except for elastic collisions with each other and with the wall at the origin. We prove that ( {Mathematical expression}, μ, Tt) is a K-flow.
