SUMMARY:On the use of Ruelle's formalism in response theory - Colangeli\, 
 M (Politecnico di Torino)

DESCRIPTION:We use Ruelles formalism to express the response of a generic 
 observable to a certain perturbation in terms of correlation functions com
 puted with respect to the unperturbed invariant measure\, for deterministi
 c as well as stochastic dynamics. We discuss the onset of two relevant ter
 ms for the entropy production\, comment on the Hamiltonian version of the 
 resulting formulae and also propose a connection with similar results\, re
 ported in the literature\, allowing to extend the Fluctuation-Dissipation 
 formalism to nonequilibrium steady states.\n
