Chaotic hypothesis: Onsager reciprocity and fluctuation--dissipation 
theorem
(70K, Postscript)

ABSTRACT.  It is shown that the "chaoticity hypothesis", analogous to Ruelle's
principle for turbulence and recently introduced in statistical
mechanics, implies the Onsager reciprocity and the fluctuation
dissipation theorem in various reversible models for coexisting 
transport phenomena.
