摘要
根据S-紧性概念,讨论了空间S-紧性的一些性质,并对其进行了等价刻划,得到若空间为S-紧的,则一定是紧的.同时还讨论了S-紧性在一定映射下的保持性问题.
On the basis of the concept of S-compactness, some properties of S-compact space are discussed. This paper gives an equivalent description of S-compact. It shows that if a space is S-compact , then it must be a compact one. The preservativeness of S-compactness under certain mappings is also discussed.
