摘要
本文定义了Fuzzy自反关系中的不动点、首元和拟首元等概念,获得了不动点与首元和拟首元间的若干性质,最后给出了D_R上n首元关系R的λ-截关系的概念,并得到了n首元关系的λ-截关系集合中R_λ^((n))的个数的计算公式.
In this paper are defined the fixed points, leading elements and quasileading elements in fuzzy reflexive relation, the properties bewteen which are obtained, and the formulae of the number of 位-cut relations are established.
