General Topology III

The problem of metrization of topological spaces has had an enormous influence on the development of general topology. Singling out the basic topo­ logical components of metrizability has determined the main reference points in the construction of the classification of topological spaces. These are (pri­ marily) paracompactness, collectionwise normality, monotonic normality and perfect normality, the concepts of a stratifiable space, Moore space and u­ space, point-countable base, and uniform ba
