Px. Chen, SIGMA-WEAKLY CLOSED MODULES OF CERTAIN REFLEXIVE OPERATOR-ALGEBRAS, Proceedings of the American Mathematical Society, 123(6), 1995, pp. 1751-1756
Let A be a completely distributive CSL algebra and let M be any sigma-
weakly closed A-module. We give characterizations of commutant C(A, M)
of A modulo M and AlgLatM. Furthermore, we deal with the relations am
ong A, C(A, M) and AlgLatM.
