The purpose of this paper is to explain the unusual isotope coefficients of cuprates by considering the influence of a pseudogap and phononic and electronic interactions in weak-coupling limit. Exact analytic expressions of the isotope exponent (a) for the s-and d-wave pairing symmetry are derived.
The differences and similarities between the different high-To superconductors are examined within the framework of the phenomological Ginzburg-Landau theory. It is argued that most of the "real" changes in the Tc's of the superconductors are due to changes in the interlayer (between unit cells) cou
