Relevance of initial and final conditions for the Fluctuation Relation in Markov processes
Numerical observations on a Markov chain and on the continuous Markov process
performed by a granular tracer show that the ``usual'' fluctuation relation for
a given observable is not verified for finite (but arbitrarily large) times.
This suggests that some terms which are usually expected to be negligible, i.e.
``border terms'' dependent only on initial and final states, in fact cannot be
neglected. Furthermore, the Markov chain and the granular tracer behave in a
quite similar fashion.Comment: 23 pages, 5 figures, submitted to JSTA
