Abstract
A theory of heavy-fermion superconductivity is proposed based on a tensor-boson condensation within an SU(N) Anderson-lattice model in which f0, f1, and f2 states are allowed. The order parameter is a multiplet for N>2. In an s-wave model, a Kondo-like expression for the gap is obtained, and Tc and Hc are calculated. Estimates for CeCu2Si2 give Tc of the correct order of magnitude.
