Aiming at a realistic description of highly excited states in semiconductors the derivation of kinetic equations is reformulated where emphasis is laid on the consideration of many-body effects without perturbation expansion arguments. By the variational derivation technique a set of equations for t

Nonequilibrium Green's function technique is applied to the many-exciton system under the action of an externally driven light field. Starting with Dyson's equation for the nonequilibrium exciton propagator the shift and damping of exciton-levels due to exciton-exciton interaction are calculated in
