摘要：

We summarize a novel approach to the periodic Anderson model in the slave-boson representation, in which the effective interactions among heavy fermions are discussed within the Hamiltonian formalism. The constraint (Lagrange) multipliers are regarded as Bose fields, Relatively strong singlet pairing and the Kondo-type coupling are mediated by the virtual exchange of slave-boson fluctuation.
