中文摘要

本文引入并研究了连续广义度量空间。本文首先证明了对于连续的广义度量空间,c-Scott拓扑和广义Scott拓扑相等,然后其次证明了连续度量空间之间的非扩张映射Yoneda连续当且仅当它关于广义Scott拓扑连续.

英文摘要

Continuous generalized metric spaces are introduced and investigated in this paper. It is shown that for such spaces, the generalized Scott topology is equal to c-Scott topology, and that a non-expansive map between such spaces is Yoneda continuous if and only if it is continuous with respect to the generalized Scott topology.
