摘要
运用代数学与模糊集的基本原理和运算方法深入研究有界Heyting代数的扩张模糊LI-理想理论。在有界Heyting代数(H,≤→ ,0,1)中,引入了模糊LI-理想∫关于H上的模糊子集κ的扩张模糊LI-理想和不变模糊LI-理想概念,给出了扩张模糊LI-理想和不变模糊LI-理想的若干重要性质和等价刻画;讨论了扩张模糊LI-理想与生成模糊LI-理想之间的关系;考查了扩张模糊LI-理想在构造格结构研究中的应用,证明了有界Heyting代数(H,≤,→ ,0,1)的模糊LI-理想全体之集FLI(H)的三类子集在模糊集合包含序■下均构成完备Heyting代数。
This paper studies, the theory of fuzzy LI-ideals in bounded Heyting algebras using the principles andoperation methods of algebra and fuzzy sets.The notions of expand fuzzy LI-ideal and invariant fuzzy LI-ideal of a fuzzyLI-ideal associated with a fuzzy subset κ in a bounded Heyting algebra (H,≤→ ,0,1)are introduced.Some importantproperties and equivalent characterizations of expand and invariant fuzzy LI-ideals are given. The relation betweenexpand fuzzy LI-ideals and generated fuzzy LI-ideals is discussed.The application of expand fuzzy LI-ideals in studyingof lattice structures is investigated, and we prove that three type subsets of the set FLI (H) which containing all fuzzyLI-ideals in a bounded Heyting algebra (H,≤,→ ,0,1), under fuzzy set-inclusion order■, are form complete Heytingalgebras.
