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 base. The method of covers has taken up a leading role in this classification. Of paramount significance in the applications of this method have been the properties of covers relating to the character of their elements (open covers, closed covers), the mutual dispo sition of these elements (star finite, point finite, locally finite covers, etc. ), as well as the relations of refinement between covers (simple refinement, refine ment with closure, combinatorial refinement, star and strong star refinement). On this basis a hierarchy of properties of paracompactness type has been sin gled out, together with the classes of spaces corresponding to them, the most important of which is the class of | | 出版日期 | Book 1995 | | 关键词 | Compactness; Funktionenraum; Gleichmäßige Konvergenz; Kompaktheit; Mengenoperationen; Metrisierbarkeit; Pr | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-662-07413-8 | | isbn_softcover | 978-3-642-08123-1 | | isbn_ebook | 978-3-662-07413-8Series ISSN 0938-0396 | | issn_series | 0938-0396 | | copyright | Springer-Verlag Berlin Heidelberg 1995 |
