前叶类共尾结构的分类
A classification of the cofinal structures of precompacta
摘要:
给出了一般度量空间中的预紧(全有界)集族和一般完全度量空间中的紧集族的可能共尾结构的一个完全分类.利用这种分类,我们对完全度量空间$X$上连续实值函数群$\C(X,\bbR)$的局部基的共尾结构,在紧开拓扑下进行了分类.
英文摘要:
We provide a complete classification of the possible cofinal structures of the families of precompact (totally bounded) sets in general metric spaces, and compact sets in general complete metric spaces. Using this classification, we classify the cofinal structure of local bases in the groups $\C(X,\bbR)$ of continuous real-valued functions on complete metric spaces $X$, with respect to the compact-open topology.
