Electronic model for superconductivity
(27K, LATeX)

ABSTRACT.  We consider a model of strongly correlated electrons that exhibits
superconductivity. It differs from the Hubbard model by nearest
neighbour interactions. We find the ground state wave function
(in one, two or three dimensions) and show it to be superconducting for
attractive and moderately repulsive on-site interaction.
