Abstract : For an infinite linear chain the authors consider the atomic limit of an extended Hubbard model which takes into account the nearest neighbor interatomic electron-electro repulsion. The specific heat, static magnetic susceptibility, and density-density correlation function are studied exactly at any temperature for the half-filled band case. The authors discuss also the quarter-filled band in the limit of infinite intra-atomic Coulomb repulsion. (Author)
