We develop exact fermion transformations which can deal with strong local Coulomb repulsions. A new basis is chosen where the effective local repulsion is much smaller, coming from a combination of level separation energies and hybridisation energies. The new representaion of fermions with weaker l
Superconductivity above 25 K, and possibly above 40 K, has recently been discovered in LaO 1Γx F x FeAs and related compounds. We propose that this is another example of the mechanism of hole superconductivity at play. This requires the existence of hole carriers at the Fermi energy, which appears t
