Some questions concerning reduced density operators are reviewed. A new proof of the condition for Fermionic N-representability of one-particle density operators is given which is based on the functional analytic method of the dual cone. The application of a quantum analog of de Finetti's theorem to
Explicit formulae are given for the number of Clar structures, C (which represent maximal independent sets of vertices), of several classes of corona-condensed polyhex systems (primitive coronoids). There is a striking equivalence between expressions for c and K, the KekulC counts for the classes re
