Abstract
Starting from a Kondo-lattice-type description, superconductivity and spin-density-wave coexistence is studied in the heavy-fermion systems. It is shown that the coexistence is energetically stable only in the presence of a supplementary ΔQ superconducting order parameter connected to the 〈ak,−σa−k−Q,σ〉-type average, where Q is the nesting wave vector.
