The (non-)Gibbsian nature of states invariant under stochastic
transformations
(44K, LATeX)

ABSTRACT.  We investigate the Gibbsian nature of systems that
are invariant under some stochastic transformation.  A prime example
concerns stationary measures for
interacting particle systems.  We bring together various types of results
concerning this question using
entropy techniques and large deviation estimates.
