Abstract

In this paper it is illustrated how to compute the time--average of a generic dynamical variable in the limit of large systems. It is also shown how to use this result to deduce an analogue of the second principle of thermodynamics, even in presence of metastable phenomena, for which it is not granted that the standard Gibbs measure can be used.
