  The Marginal Fermi Liquid (MFL) hypothesis proposed by Varma et al is derived
from a consistent treatment of local spinfluctuations in the Falicov-Kimball
model (FKM). Within an infinite-dimensional mean-field approach, a marginal
Fermi liquid susceptibility and single-particle self-energy are obtained near
half-filling, and a Fermi liquid phase is recovered sufficiently away from
half-filling, in agreement with indications from experiments which probe the
normal state of the cuprates as a function of doping
