We present a detailed analysis of the kinetic behaviour of a one-dimensional Rayleigh model, consisting of one hard point interacting with otherwise freely moving points. We generalized the previous work of Jepsen and others by taking into account initial correlations between the particles; we...

The relation of the linearized hydrodynamic equations to kinetic theory is discussed. We show that the theory of subdynamics provides a general framework for their derivation. This theory and the related transformation theory permit the construction of a Lyapounov functional that for the...
