Аннотация: The problem of Cooper instability is studied by implementing the Kohn–Luttinger mechanism in the frame-work of the Shubin–Vonsowsky model taking into account the intersite Coulomb interactions within the first and second coordination spheres. It is shown that the Kohn–Luttinger renormalization for the effective interaction in the second order terms of perturbation theory, as well as the inclusion of intersite hoppings in the second and third coordination spheres, significantly affects the interplay between the superconducting phases with dxy-, p-, s-, and dx2-y2 -wave symmetries of the order parameter.
