The Drude weight {ital D} and the dc conductivity {sigma}{sub dc}({ital T}) of strongly correlated electrons are investigated theoretically. Analytic results are derived for the homogeneous phase of the Hubbard model at {ital d}={infinity}, and for spinless fermions in this limit with 1/{ital d} corrections systematically included to lowest order. It is found that {sigma}{sub dc}({ital T}) is finite for all {ital T}{gt}0, displaying Fermi-liquid behavior, {sigma}{sub dc}{proportional_to}1/{ital…
