Summary, Conclusions, and Critical remarks

Abstract

In the work presented in this book, we have developed an electronic theory for singlet Cooper pairing in the high-$T_c$ cuprates and for triplet Cooper pairing in $\mbox{Sr}_2\mbox{RuO}_4$ due to spin excitations. In particular, we have studied the corresponding phase diagrams, the symmetry of the superconducting order parameter, and the elementary excitations of these materials in both the normal and the superconducting state. In this chapter, we summarize and discuss our main results and arguments and illustrate them in a few figures. We also discuss what would be the additional role of phonons in our theory. Finally, we point out a few weak points of our theory. ...
