Abstract
The Boltzmann equation considered by Bobylev, and Krook and Wu (BKW) is rewritten in the form of a stochastic equation, similar in form to the kinetic equations of Tjon and Wu, and Ernst. A new class of models, which reflects the transformation of the BKW model to other dimensionalities, is constructed, and its equilibrium distributions, non-equilibrium solutions (corresponding to the BKW mode), and H theorems are found.
