✦ Synopsis

We consider the model of supegconducting pairing with the energy gap function which is odd over k -kp. In this case superconductivity is possible even in the presence of an arbitrarily large point-like repulsion between electrons. We discuss mainly a model pairing interaction for which the BCS equations can be solved exactly, allowing the complete analysis of the interplay of the usual (Xeven ") and "odd ~ pairing, aOdd ~ pairing dominates for strong enough repulsion and pairing interactions. We show that the normal impurities (disorder) lead to very strong degradation of the ~odd ~ pairing, which is even more rapid than in case of magnetic impurities in traditional superconductors.
