Large deviation principle of the empirical current for Markov processes
Lorenzo Bertini (Roma La Sapienza)



Abstract:
We consider a continuous time Markov chain on a countable state space 
and extend the classical Donsker-Varadhan large deviation principle for 
the empirical measure by considering also the empirical flow. We then 
discuss the application to the Gallavotti-Cohen functional, whose 
associated large deviation principle can be obtained by projection. We 
finally illustrate briefly the analogous results for diffusion 
processes on R^n.

Macroscopic fluctuation theory for aerogels dynamics 
Mauro Mariani (Aix-Marseille III)



Abstract:
Macroscopic fluctuation theory provides a main tool to study
non-equilibrium Statistical Mechanics. In this talk, a class of models 
is introduced, for which it can be proved that the quasi-potential of 
the current fluctuations is non-analytical.
