Free objects in the category of fuzzy S-acts
摘要
Let S be a monoid. We define fuzzy independent subsets of fuzzy S-acts and use them to characterize the fuzzy basis of fuzzy S-acts. Furthermore, we prove that a fuzzy S-act is a free object in category of fuzzy S-acts if and only if it possesses a fuzzy basis. Additionally, we investigate the conditions under which a free fuzzy S-act is projective.
