Аннотация: The effect of three-center interactions on the formation of a superconducting phase with d(x2-y2)-symmetry is considered using the diagram technique for Hubbard operators and irreducible Green's functions. It is shown that these interactions lead to a decrease in T-c by a factor of several tens.
