| Abstract: | The e-ph interaction in YBaCuO is calculated and the nonlinear Eliashberg equation is solved by the newly introduced bifurcation theory and parameter imbedding method. The transition temperature is low from the traditional (RA.4) e-ph model. The cause of some authors' improper high TC result is discussed. |
