先定义了柔集的笛卡尔积,射影序同态,柔拓扑空间的基、子基等概念,在此基础上定义了乘积柔拓扑空间,给出了乘积柔拓扑空间的等价描述以及乘积柔拓扑空间的一些基本性质,证明了一族满足T0分离性(resp.,T1分离性,T2分离性,正则分离性,连通性)的柔拓扑空间的乘积柔拓扑空间仍然满足这种性质,同时证明了第二可数是犍。一可乘性质。
Firstly, the concepts of Cartesian product of the soft set, projective order-homomorphism, basis and subbasis of a soft topological space, are introduced. Based on these concepts, product soft topological space is defined, and characterizations of product soft topological spaces and basic properties of product soft topological spaces are given. It is proved that product soft topological space of a family of soft topological spaces with T0-separation (resp. , Tl-separation, Tz-separation, regular separation, connectedness) still has this kind property, and second-countability is 0-multiplicative property.
