摘要
在L-拓扑空间中通过引入θ-闭包的概念,定义θ-开(闭)集,讨论θ-闭包和θ-闭集的性质及其刻画.同时给出了两个有用的命题,证明了L-拓扑空间中全体θ-开集形成一个比原拓扑更粗的拓扑,进而引入并研究了θ-连续序同态,同时给出了θ-连续序同态的刻画,并举例说明θ-连续映射不必是连续映射.
By introducing θ-closures in L-topological spaces and defining θ-open(closed) sets,this paper discusses the properties and characterizations of θ-closures and θ-closed sets.Two useful propositions are given.It is proved that all θ-open sets in an L-topological space form a new topology which is coarser than the original one.The concept of θ-continuous order homomorphisms is introduced and discussed.θ-continuous order homomorphisms characterizations are given,and examples are provided to demonstrate that θ-continuous mapping need not be continuous mapping.
