AXIOMATIZATION OF FUZZY LOWER APPROXIMATION OPERATORS

摘要：

In paper 7, author had studied the axiomatization of general fuzzy rough sets when relations and sets are both fuzzy,and obtained axiom group of fuzzy upper approximation operator. While the discussion of fuzzy lower approximation is too complicated, they have not get corresponding axiom group.In this paper, we deduce axiom group of fuzzy lower approximation operator and prove its credibility and independence by introducing two new concepts, which are number added fuzzy sets and outside composition operations.
