模糊格中分子网的σ-收敛性

σ-convergence of Molecular Nets in Fuzzy Lattices

在模糊格中引入分子网的 σ-收敛性与 σ-闭元等概念。研究了分子网的 σ-极限点和σ-聚点的各种特征性质及其若干应用。讨论了 σ-收敛性与收敛性 ( θ-收敛性和 Urysohn收敛性 )之间的关系。

In this paper,the concepts of σ closed elements and σ convergence of molecular nets in fuzzy lattices are introduced. Some applications and various characterizations of σ limit points and σ accumulation points with respect to molecular nets are studied. The relationships between the σ convergence and the convergence ( θ convergence,Urysohn convergence) of molecular nets are discussed.
