The Gibbs entropy production in general relativity
Description
The entropy production is analyzed in the case of homogeneous cosmological models of the Bianchi type. It is shown to vanish for class-A models and to be undefined for class-B ones, because of an ambiguity in the measure on the space of the true gravitational degrees of freedom. How this results extend to the full Einstein theory is discussed
