Onsager reciprocity relations without microscopic reversibility
(18K, ApsTeX)

ABSTRACT.  In this paper we show that
Onsager--Machlup time reversal properties of thermodynamic fluctuations
and Onsager reciprocity relations for transport
coefficients can hold also if the 
microscopic dynamics is not reversible. 
This result is based on 
the explicit construction of a class of conservative models which can 
be analysed rigorously.
