DESCRIPTION:In non-equilibrium there is an enormous variety of phenomena s
 o we cannot hope to formulate a unique theory having a generality comparab
 le to classical thermodynamics. We have to restrict to subclasses of probl
 ems. Diffusion is a phenomenon almost ubiquitous and in recent years consi
 derable progress in its understanding has been obtained. One&nbsp\; diffic
 ulty is to define suitable thermodynamic functionals in far from equilibri
 um situations. Large fluctuations have offered a way out as large deviatio
 n rates provide genuine thermodynamic functionals whose singularities desc
 ribe new phase transitions some of which can take place only out of equili
 brium.
