Title: An experimental test of the local fluctuation theorem
       in chains of weakly interacting Anosov systems

Abstract:

An experimental test of a large fluctuation theorem is performed on a
chain of coupled ``cat maps''. Our interest is focused on the behavior
of a subsystem of this chain. A local entropy creation rate is
defined and we show that the local fluctuation theorem derived in
[G1] is experimentally observable already for small subsystems.
