Abstract
A method to describe the effects of the exciton-optical phonon interac tion is presented using tile cumulant expansion approximation. The fun ctional-integral technique of coherent phonon states is used in order to justify tile commonly used model Hamiltonian and generate tile prop er perturbation series. The influence of the mutual electron-hole scre ening on the polaronic effects in quantum wells is analyzed.
