An exact kinetic equation governing the time evolution of a gas of Bosons interacting with a heat bath is derived by master equation techniques. Its solution is shown to exist globally and to converge to equilibrium; a Liapunov functional is construc

We study a non-linear integro-differential equation describing the evolution of a gas of Bosons interacting with a heat bath. The solution is shown to exist globally. A family of Liapunov functionals is constructed and used to prove convergence to eq

We derive the rules for collisions between hard spheres in arbitrary dimensions in the isobaric-isoenthalpic ensemble. The static and time-dependent properties of the one-dimensional hard rod system are investigated in detail, both theoretically and

A simple first-order Kikuchi approximation is studied for the short-range (nearest-neighbour) version of the van Hemmen mean-field model originally proposed for spin-glasses. Although the approximation is very similar to the mean-field treatment, the

The exactness of the Bogoliubov approximation is discussed from the point of view of the condensation properties of the Bose gas. For the imperfect Bose gas, the authors find that the approximation yields the correct condensate density when the therm

An Ising spin-glass calculation is presented showing that stable "reentrant" spin-glass behavior, which is absent in mean-field theory, occurs when local correlations are taken into account. The method is a simple Kikuchi approximation starting from

We prove that the KMS condition for the infinite ideal Bose gas at any temperature 1/β and chemical potential μ⩽0 implies regularity under certain conditions on the test function space. Also, explicitly irregular solutions are constructed indicat

In this article we demonstrate that the Gibbs ensemble and the canonical ensemble are equivalent in the thermodynamic limit. Furthermore, we discuss some interesting aspects of the method when applied close to the critical point. We show that for a f
