Query: Kondo Effect in a Metal with Correlated Conduction Electrons   The large-degeneracy expansion for dilute magnetic alloys is extended to
account for conduction electrons interactions. Particular attention is paid to
the renormalization of the hybridization vertex which affects the low-energy
excitations. As a first example, we calculate the enhanced characteristic
energy $k_BT_0$ in the limit of weakly correlated conduction electrons. The
metallic regime with strongly correlated electrons is discussed.
