It is shown that the Nussinov–Rosner method for diagonalization of ladder equations for the absorptive part of forward scattering amplitude is an approximate method for the high energy region and is inapplicable for obtaining the exact solutions. Method of diagonalization of ladder equations is proposed, which is based on the reduction of the: equations to partial differential equation.
