Abstract
We investigate the metal-non-metal transition due to correlations between electrons in narrow energy bands. Using a functional integral formalism, we study Hubbard's model. The insulating properties are found to be consequences of magnetism. At low temperature the splitting of the band is due to antiferromagnetism. Above the Nél temperature, it is due to the formation of local moments on each site.Keywords
