摘要: We have taken into consideration the Eliashberg equations based on electron-phonon and electron-electron-phonon interaction. It has been shown that set generalizes model canonical transformation, which for cuprates quantitatively associates with each other critical temperature (T C ), Nernst ⋆⋆), energy gap at 0 K. Next, we derived analytical formulas basic thermodynamic parameters. The conducted analysis allowed to designate T - ⋆⋆ diagram. Finally, found limitation from below value of ⋆⋆, occurring higher than 150
