Positivity of entropy production in the presence of a random thermostat.
(37K, TeX)
ABSTRACT. We study nonequilibrium statistical mechanics
in the presence of a thermostat acting by random forces, and propose a
formula for the rate of entropy production $e(\mu)$ in a state $\mu$.
When $\mu$ is a natural nonequilibrium steady state we show that
$e(\mu)\ge0$, and sometimes we can prove $e(\mu)>0$.
