Abstract

The effect of three-center interactions on the formation of a superconducting phase with \(d{x^2-y^2} \) 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.
