  In this paper we prove the strong and time-averaged strong convergence to
equilibrium for solutions (with general initial data) of the spatially
homogeneous Boltzmann equation for Fermi-Dirac particles. The assumption on the
collision kernel includes the Coulomb potential with a weaker angular cutoff.
The proof is based on moment estimates, entropy dissipation inequalities,
regularity of the collision gain operator, and a new observation that many
collision kernels are larger than or equal to some completely positive kernels,
which enables us to avoid dealing with the convergence problem of the cubic
collision integrals.
