We study work production in a Markov system obeying discrete stochastic dynamics. As our main result, we establish a new equality concerming C the work produced during a spontaneous transformation in an isothermal, non-equilibrium system. Then we consider the overall evolution of a non-equilibrium system driven by an external parameter and generalize Jarzynski's equality for systems maintained out of equilibrium. That equality is recovered if the initial and final state distributions are equilibriums. (c) 2008 Elsevier B.V. All rights reserved.
