The Weighted Embedded Homology of Super-Hypergraphs
《Wuhan University Journal of Natural Sciences》2024年第6期523-528,共6页WANG Chong 
Supported by the Science and Technology Project of Hebei Education Department (ZD2022168);the Research and Innovation Team of Cang‐zhou Normal University (cxtdl2304)。
In this paper,we define the weighted embedded homology of super-hypergraphs,give a quasi-partial order and a pseudo-metric on the set made up of all non-vanishing weights on a finite set,and clarify the relationship b...

A NOTE ON ISOMETRIC METRIZATION OF PROBABILISTIC METRIC SPACES
《Chinese Science Bulletin》1991年第18期1497-1500,共4页方锦暄 
The metrization of a probabilistic metric space (for short, PM-space )usually implies the metrization of its (ε,λ)-topological structure. Therefore, if a PM-space is metrizable, it only implies that its topological ...
