Extension of Onsager's reciprocity to large fields and the 
chaotic hypothesis

Abstract: The fluctuation theorem, the first 
consequence of the Chaotic Hypothesis of [GC1], is
shown to yield an extension to arbitrary forcing
fields of the Onsager reciprocity (OR) (and of the
corresponding fluctuation dissipation theorem
(FD)) in a wide class of nonequilibrium
statistical mechanical systems.

Keywords: Onsager reciprocity, fluctuation dissipation, 
chaotic  hypothesis, Ruelle principle, chaos, strange 
attractors, nonequilibrium, statistical mechanics.
