L—Fuzzy群（I）

In this paper,the L-fuzzy group theory in a general frame is established,which is a generalization of [1-4].     

LF λ-subgroup Generated by LF Subset

In this paper .an important property layer-preserving of LF group and an concept LF λ-subgroup generated by LF subset will be introduced. On the height of LF group theory ,we recognize the concept generated subgroup more clearly.     

LF拓扑空间之间投影映射是开映射的一个充要条件

王国俊先生曾提出这样一个问题：设｛（Ｌ＾Ｘ，δｔ）｝ｔ∈Ｔ是一族ＬＦ拓扑空间，（Ｌ＾Ｘ，δ）是其乘积空间，Ｐｔ：Ｌ＾Ｘ→Ｌ＾Ｘｔ（ｔ∈Ｔ）是投影映射，问Ｐｔ是开映射的充要条件是什么？本文在较广范围－形如（Ｌ＾Ｘ，η）的拓扑分子格－内讨论类似问题，给出了上述问题的一个解答。

排列组合中一类分组分配问题的统一球盒模型

本文研究了排列组合中一类分组分配问题,形式化成三个球盒模型,引入三个符号既表示这三种模型又表示模型对应的方案数.三模型可以统一快捷地解答平均分组和不定向分配等问题,为实际应用的分析理解和解答带来方便.

格蕴涵代数的LI-理想空间

In this paper,a topological space based on LI-ideals of a lattice implication algebra is constructed,and its topological properties,such as separability,compactness and connectedness are discussed.     

分层有限偏序集的直积

A new concept Graded Finite Poset is proposed in this paper.Through discussing some basic properties of it,we come to that the direct product of graded finite posets is connected if and only if every graded finite poset is connected.The graded function of a graded finite poset is unique if and only if the graded finite poset is connected.     

L—fuzzy群（Ⅱ）

This paper is a continuation of [1].In paper[1],the concept of LF group was introduced.In this paper,the concept of OP homomorphism will be introduced and its properties will be discussed.
