Résumé : In an extension of the formalism developed by I. Prigogine and his collaborators, we derive the generalized equations of evolution for a system in the presence of an external field, of arbitrary strength and time dependence, but uniform in space. The basic new feature of both the non-Markoffian and the asymptotic equations consists in the field dependence of the collision term. The explicit form of these field corrections is worked out for a simplified description of a plasma in a constant electric field, and the limit of validity of the usual kinetic equations is specified. The generalized equation of evolution introduces a corrective term linear in the electric field which, for the stationary state, is precisely such as to ensure the complete equivalence with the linear response function formulation of the stationary state, i.e. with the Kubo formula. © 1957.
