本文研究了局部紧非紧可分度量空间Xin可度量紧化的类。对于每一个整数n_n ~ 1,我们描述了具有Cain,Jr.意义上的补性质的空间X的类。然后证明了对每个α<ω 1,存在局部紧的非紧可分可度量化空间H α,使得H α是所有类族中的严格增序列。
We consider the classesof remainders of locally compact noncompact separable metrizable spacesXin metrizable compactifications. For each integern≧1 we describe the classesof spacesXadditionally having then-complementation property in the sense of Cain, Jr. Then we show that for eachα<ω1there is a locally compact noncompact separable metrizable spaceHαsuch thatis a strictly increasing sequence in the familyof all classes.
