    "abstract": "We consider the pairing Hamiltonian and systematically construct its density\nfunctional in the strong-coupling limit and in the limit of large particle\nnumber. In the former limit, the functional is an expansion into central\nmoments of occupation numbers. In the latter limit, the functional is known\nfrom BCS theory. Both functionals are nonlocal in structure, and the\nnonlocalities are in the form of simple products of local functionals. We also\nderive the relation between the occupation numbers and the Kohn-Sham density.",
