The Origin of Generalized Metric Spaces,s or their extensions and generalized countable compactness. At the same time, we give some simple characterizations of these spaces, describe their basic operation properties, such as hereditary properties, productive properties and properties preserved under topological sums, and discuss their pre

Generalized Metric Spaces,rties remain unchanged (see Question 2.0.6). One of the central topics of this chapter is to determine the given classes of generalized metric spaces are preserved by which kinds of mappings. Therefore, we must fully investigate various properties of generalized metric spaces. One of the most wonder
