摘要
在已有M-模糊化拟阵的研究基础上,引入了M-模糊化秩函数及M-模糊化P-闭包算子的定义,研究了M-模糊化P-闭包算子的性质,并定义了M-模糊化P-闭集族及研究了它的基本性质,同时借助于M-模糊化拟阵的层拟阵结构,得到M-模糊化拟阵可由M-模糊化P-闭集族等价刻画这一结论.
In this paper, based on existing research of M-fuzzifying matroids, by the defi- nitions of M-fuzzifying rank function and M-fuzzifying P-closure operators, some properties of M-fuzzifying P-closure operators are shown, and the notion of M-fuzzifying family of P- closed sets is defined, then its properties are found. By the cuts of M-fuzzifying matroid, it is proved that M-fuzzifying matroid can be expressed by M-fuzzifying family of P-closed sets. In short, it is a true that there is one-to-one corresponding between M-fuzzifying matroid and M-fuzzifying P-closure operators or M-fuzzifying family of P-closed sets.
