Abstract
Using the diagram technique for the Hubbard operators an integral equation that determines the order parameter of the superconducting phase Î(p) was obtained in the framework of t-J-V and t-J*-V models on triangular lattice. It is shown that there are two scenarios of formation of superconducting phase with gapless spectrum at the critical concentration of carriers xc. The effect of three-center terms on implementation of this phase was also considered.
