"The stationary behavior of type II superconductors is completely described by Gorkov's equations for a set of four Green's functions, supplemented by two self-consistency equations for gap parameter\u0394(r) and vector potentialA(r). Expanding all quantities as usual at the Fermi surface and averaging over impurity positions, this set of equations is transformed into a simpler set for integrated Green's functions (which still contain much more information than is needed in most cases). The resulting equations, when linearized, yield essentially L\u00FCders' transport equation for de Gennes' correlation function. The full equations contain all the known results and provide a promising starting point for numerical calculations.The thermodynamic potential is constructed as a functional of the integrated Green's functions and the mean fields\u0394 andA and a variational principle is formulated which uses this functional. Finally, paramagnetic scatterers are included (in Born approximation) as an example for possible generalizations of the new equations." .
