Abstract. We study the solvability of certain linear nonhomogeneous equations containing the logarithm of the sum of the two Schrodinger operators in higher dimensions and demonstrate that under the reasonable technical assumptions the convergence in L^2(R^d) of the right sides yields the existence and the convergence in L^2(R^d) of the solutions. The equations involve the operators without the Fredholm property and we use the methods of the spectral and scattering theory for the Schrodinger type operators to generalize the results of our preceding work [19]. As distinct from the many previous articles on the subject, for the operators contained in our equations the essential spectra fill the whole real line.
