报告题目：Morita theory for the category of S-acts and the category of fuzzy S-acts
报告摘要：Morita equivalence theory characterizes the relationship of module categories of two rings with 1, which is very useful in studying ring theory. Hom functors and tensor product functors play an important role in the study of Morita theory. Also, these two functors are important in areas of abstract algebra, homological algebra and ring. Morita theory has also been extended to semigroup theory and fuzzy ring theory. We shall introduce some results on Morita equivalence of semigroups and some properties of Hom functors and tensor product functors in the category of fuzzy S-acts.
