Abstract
A two-dimensional Kondo lattice with inter-site interaction is studied using a canonical transformation to eliminate interactions. Our appro ach is patterned on Bardeen and Pines' elimination of electron-phonon interaction. It is shown that interactions are eliminated at nonzero t emperatures in the thermodynamic limit, in a manner differing radicall y from the case of phonons.
