Abstract. The Gallavotti-Cohen fluctuation theorem suggests a general symmetry in
the fluctuations of the entropy production, a basic concept in the
theory of irreversible processes, based on results in the theory of
strongly chaotic maps. We study this symmetry for some standard models
of nonequilibrium steady states. We give a general strategy to derive a
Local fluctuation theorem exploiting the Gibbsian features of the
stationary space-time distribution. This is applied to spin flip
processes and to the asymmetric exclusion process.
