Abstract
A theory of heavy-fermion superconductivity is proposed based on a tensor-boson condensation within an Anderson-lattice model in which , , and states are allowed. The order parameter is a multiplet for . In an -wave model, a Kondo-like expression for the gap is obtained, and and are calculated. Estimates for Ce give of the correct order of magnitude.
