Abstract
I propose a method, based on a set of Langevin equations, for bringing classical gauge theories to thermal equilibrium while respecting the set of Gauss' constraints exactly. The algorithm is described in detai l for the SU(2) gauge theory with or without the Higgs doubler. As an example of an application, the canonical average of the maximal Lyapun ov exponent is computed for the SU(2) Yang-Mills theory.
