Title: Note on Two Theorems in Nonequilibrium Statistical Mechanics

Abstract: An attempt is made to clarify the difference between a theorem
derived by Evans and Searles in 1994 on the statistics of trajectories
in phase space and a theorem proved by the authors in 1995 on the
statistics of fluctuations on phase space trajectory segments in a
nonequilibrium stationary state.

Keywords: Chaos, chaotic hypothesis, large deviations, fluctuations,
time reversal
