At first, both the concepts of fuzzy set and fuzzy re-lation are given, and the convergence of fuzzy matrices is introduced. 我們從模糊集與模糊關(guān)系的概念開(kāi)始，引出模糊矩陣冪序列的收斂性問(wèn)題。
On inverse semi-groups, the fuzzy normal sub-semigroup and fuzzy quotient sub-semigroup are defined via some special fuzzy relation by using fuzzy congruence relation on set. 摘要利用集合上模糊同余關(guān)系，在逆半群上定義了模糊正規子半群和模糊商子半群，并研究了逆半群上由這幾類(lèi)模糊關(guān)系所定義的模糊同余關(guān)系的一些性質(zhì)。
