摘要：

A unified approach to superconductivity is presented using natural extensions of weak coupling BCS theory. Multiphonon-multiband interactions cause a multigap opening at T(c), with cooperative pairing in all bands incorporated via interband interactions. Strong increases in T(c) are found due to interband-induced gap coupling. Model calculations for the experimentally observed gap distribution are presented.
