A quantikr is introduced on the elements e, , . .". The sr;qtroid dual of this quantifier is sholvn to be identical with its logkal dual, and this provides an elegant reformulation of Minty's sd2lf+iual axiomatization of mat&is. This approach also provides a practical, and in a sense optimal, n~ans
The duality of infinite matroids with coefficients defined in [1] and the duality of Klee matroids [5], a generalization to the infinite case of matroid closure operators, are not identical. In this paper we characterize those Klee matroids arising as closure operators of matroids with coefficients.
