On the Direct Decomposability of QL-Implication Operators on Product Lattices
Zhudeng Wang · 2007
In this paper, we further study the direct decomposition of implication operators on product lattices, discuss the decomposability of QL-implications on product lattices and show that QL-implications is a direct product of two implication operator when it satisfies the law of right (or left) contraposition with respect to a strong negation.
