Keywords: | Ordered (preordered) topological spaces; Priestley space; Stone space; Regular and universal regular epimorphisms; (ef ective) descent morphisms; Monadic categories | Issue Date: | 2005 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 05-04 (2005) | Abstract: | A characterization of descent morphism in the category of Priestley spaces, as well as necessary and su cient conditions for such morphisms to be e ective are given. For that we embed this category in suitable categories of preordered topological spaces were descent and e ective morphisms are described using the monadic description of descent. | URI: | https://hdl.handle.net/10316/11393 | Rights: | openAccess |
