Title: | Descent for discrete (co)fibrations | Authors: | Sobral, Manuela | Keywords: | Descent data; (e ective) descent morphisms; (co) fibrations; Discrete (co)fi brations; Lax epimorphisms | Issue Date: | 2003 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 03-05 (2003) | Abstract: | We characterize the (e ective) E-descent morphisms in the category Cat of small categories, when E is the class of discrete fibrations or the one of discrete co fibrations, and prove that every e ective global-descent morphism is an e ective E-descent morphism while its converse fails. | URI: | https://hdl.handle.net/10316/11440 | Rights: | openAccess |
