The Quillen Model Category of Topological Spaces
We give a complete and careful proof of Quillen’s theorem on the existence of the standard model category structure on the category of topological spaces. We do not assume any familiarity with model categories.
متن کاملDomain Representations of Topological Spaces (extended Abstract)
A domain representation of a topological space X is a function usually a quotient map from a subset of a domain onto X Several di erent classes of domain representations are introduced and studied It is investigated when it is possible to build domain representations from existing ones It is for example discussed whether there exists a natural way to build a domain representation of a product o...
متن کاملOn Some Generalized Structures in Fuzzy Soft Topological Spaces
Molodstov introduced soft sets to deal with uncertainties and not clear objects. Researchers developed the relationship between soft sets and information systems. Fuzzification of the notions of soft sets and soft topology have been discussed in the literature. In this paper, we define and establish the topological structures of fuzzy soft semi-open sets and fuzzy soft semi-closed sets. We intr...
متن کاملOn Some Uniform Type Structures in Fuzzy Topological Spaces
Two generalized uniform structures namely fuzzy quasi-uniformity and fuzzy local quasi-uniformity are introduced. Conditions of fuzzy quasi-uniformizability and quasi-metrizability are examined. Mathematics Subject Classification: 54E15, 54A20
متن کاملEpimorphisms in the Category of Hausdorff Fuzzy Topological Spaces
In this paper we have characterized the epimorphisms in the full subcategory of Hausdorff fuzzy topological spaces (introduced by Srivastava et al.[10]) of the category FTS of fuzzy topological spaces and fuzzy continuous functions using the Salbanytype closure operator.
