Fuzzy格的分支构造 总被引:6,自引:0,他引:6
本文的主要结论是:一切Fuzzy格皆由极小分支构成,极小分支则由素元组成。具体地说,本文以正交集为工具,引入了分支,极大、极小分支的概念。证明了极小分支的每个非零元为素元。属于同一极小分支的各素元彼此都不正交,而属于不同极小分支里的素元彼此一定正交,每个Fuzzy格必存在极小分支的完全族。Fuzzy格的每个元素都可向极小分支投影,并且等于各投影的并。即Fuzzy格的各个元可以一意地表成彼此正交的若干素元的并。特别,对于正统Fuzzy格,每个分支的最大元必为分明元,反之每个分明元的下集必是一个分支。分明元与分支一一对应。极小分明元对应于极小分支。在极小分支里,由原来的补结构,可以诱导建立极小分支里的补结构。这时的极小分支也成为一个Fuzzy格(它只有一个分支)。当且仅当这些极小分支Fuzzy格彼此同构时,原Fuzzy格才与L-Fuzzy集同构(即Fuzzy格退化为L-Fuzzy集);当且仅当每个极小分支由一个元素组成时,正统Fuzzy格退化为Boolean代数(格)。非退化的正统Fuzzy格的主要特征在于它有非分明元。正统Fuzzy格不同于L-fuzzy集主要是它的极小分支可以不同构。 相似文献

A topological molecular lattice (TML) is a pair (L, T), where L is a completely distributive lattice and r is a subframe of L. There is an obvious forgetful functor from the category TML of TML‘s to the category Loc of locales. In this note,it is showed that this forgetful functor has a right adjoint. Then, by this adjunction,a special kind of topological molecular lattices called sober topological molecular lattices is introduced and investigated. 相似文献

This paper is devoted to the discussion of filters in residuated lattices. The lattice structure of filters in residuated lattice was established. It is proved that the set of all filters forms a distributive lattice. Also, the concept of prime filter in residuated lattice was proposed and some equivalent conditions about prime filter were given. 相似文献

We study lattice theoretical properties of lattices of uniformities such as modularity, distributive laws and the existence
of (relative) complements. For this the concepts of permutable uniformities (see Definition 3.1) and independent uniformities
(see Definition 4.1) are important. Moreover, we show that e.g. the lattice of all lattice uniformities on a lattice L is a closed sublattice of the lattice of all uniformities on L. 相似文献
