Abstract The coupling between the charge transfer and the lattice fluctuations is proposed as a possible mechanism of the superconductivity in the polaron system near the cross-over from the quasi-localized to the delocalized regime. The corresponding self-energy matrix is deduced using the Holstein Hamiltonian and the equations for the off-diagonal order are formulated. The lower bound on the superconducting critical temperature is estimated and the possible relevance of the proposed mechanism for the superconducting copper oxides is discussed.
