The discovery of high T c superconducting cuprates occurred over a decade ago but the cause of the superconducting condensation and electronic structure of such compounds is still a matter of considerable debate. While there is no agreement as to the pairing mechanism, there is, on the other hand, a wide consensus about the main properties which a theoretical description should provide. In this article, a theory is presented which accounts in a straightforward way for many of the essential properties of the high T c cuprate superconductors. Some further developments of the model are suggested, particularly relating to the normal state spin‐gap which our model does not currently describe. ©1999 John Wiley & Sons, Inc.
