| Résumé : | A new, explicitly time-dependent formulation of subdynamics is presented for the treatment of irreversible processes in non-equilibrium statistical mechanics. The theory generalises the subdynamics concept from the case where the Liouville superoperator is time independent to include the situation in which it may possess an explicit time dependence. The scope of the approach is considerably broadened thereby; as one particular consequence, the non-unitary ('star-unitary') transformation theory of the Brussels school may be extended to deal with large systems interacting with time-dependent external fields. Hence a unified description of irreversibility in both isolated and open systems begins to emerge. © 1988 IOP Publishing Ltd. |
