Title: | Descent for compact 0-dimensional spaces | Authors: | Janelidze, George Sobral, Manuela |
Keywords: | Comma categories; Effective descent; Effective F-descent | Issue Date: | 2008 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 08-38 (2008) | Abstract: | Using the reflection of the category C of compact 0-dimensional topological spaces into the category of Stone spaces we introduce a concept of a fibration in C. We show that: (i) effective descent morphisms in C are the same as the surjective fibrations; (ii) effective descent morphisms in C with respect to the fibrations are all surjections. | URI: | https://hdl.handle.net/10316/11237 | Rights: | openAccess |
