Experimental studies of superconductivity properties of
fullerides are
briefly reviewed. Theoretical calculations of the electron-phonon coupling,
in particular for the intramolecular phonons, are discussed extensively.
The calculations are compared with coupling constants deduced from a number of
different experimental techniques. It is discussed why the
A_{3}C_{60}
are not Mott-Hubbard insulators, in spite of the large Coulomb
interaction. Estimates of the Coulomb
pseudopotential mu*, describing the effect of the Coulomb
repulsion on the superconductivity, as well as possible electronic
mechanisms for the superconductivity are reviewed. The calculation of
various properties within the Migdal-Eliashberg theory and attempts to
go beyond this theory are described.
