Abstract. We discuss the positivity of the mean entropy production for stochastic
systems driven from equilibrium, as it was defined previously by us
in connection with a fluctuation theorem.
Non-zero entropy production is closely linked with violation of the
detailed balance condition. This connection is rigorously obtained
for spinflip dynamics.
We remark that the positivity of entropy production depends on the
choice of time-reversal transformation, hence on the choice of the
dynamical variables in the system of interest.
