Abstract
It is shown that the properties of the superconductivity observed in SrRuO can be accounted for by properly taking into account the internal degrees of freedom of the system. The electrons are strongly correlated in the RuO planes while the superconducting phase transition is driven by ``umklapp scattering'' between the planes. The in-plane magnetic correlations are determined via a non-perturbative approach. The orbital degeneracy and the magnetic moments are internal degrees of freedom of the Cooper pairs that account for the thermodynamic properties in the superconducting phase.
