Invariance conditions which link a class of ordinary differential equations with a type of B~cklund-like transformation are developed and solved. These nonpoint transformations are used to obtain 'superposition principles' and as an illustration of their consequences a derivation of the duplication

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
