不分明化拓扑中的θ－闭包

ON θ CLOSURE IN FUZZIFYING TOPOLOGY

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.
