Query: Testing the irreversibility of a Gibbsian process via hitting and return
  times   We introduce estimators for the entropy production of a Gibbsian process
based on the observation of a single or two typical trajectories. These
estimators are built with adequate hitting and return times. We then study
their convergence and fluctuation properties. This provides statisticals test
for the irreversibility of Gibbsian processes.
