✦ Synopsis

WC Invehtigatc the Huhhard model with infinite range hopping. The model is not equivalent to the infinite rangtz Hciscnberg model and bhows no phase transition contrary to the latter. A sufficxnt condition for the interchange of the U +x and thermodynamic limit is given. We calculate the zero tcmpcrature magnetization and conjecture the linear dependence on the filling factor for :trhitrary dimensions.
