摘要
在不分明化拓扑空间中,给出了人们广为关注的拓扑学中的θ闭包的概念,并由此定义了θ-开集、θ-闭集、θ-连续映射和强θ-连续映射.使用逻辑的语议的方法讨论了他们的有关性质,在不分明化拓扑中导入了θ-拓扑空间。
The concept of θ closure,θ open sets,θ closed sets,θ continaous mappings and θ strong continuous mapprings are introduced. By the use of methods of semantic in logic, some properties of them are discussed, and four equivalence conditions of θ strong continuous mapping and four necessary conditions of θ continuous mapping are obtained.
