摘要
给出t模糊等价关系及相应的t模糊商空间的定义,讨论其性质,证明了全体t模糊等价关系与t模糊知识基的集合构成同构的完备格。
The definition of t-fuzzy equivalent relation and its corresponding t-fuzzy quotient space are proposed in this paper. Their properties are discussed. It is proved that all the t-fuzzy equivalent relations and all t-fuzzy knowledge bases form an isomorphic complete lattice, respectively.
