Title: | On coregular closure operators | Authors: | Gutierres, Gonçalo | Keywords: | Closure operator; (co) regular closure operator; Connectedness; Preradical; Torsion theory | Issue Date: | 1999 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 99-21 (1999) | Abstract: | Among closure operators in the sense of Dikranjan and Giuli [5] the regular ones have a relevant role and have been widely investigated. On the contrary, the coregular closure operators were introduced only recently in [3] and they need to be further investigated. In this paper we study co regular closure operators, in connection connectednesses and disconnectednesses, in the realm of topological spaces and modules. | URI: | https://hdl.handle.net/10316/11480 | Rights: | openAccess |
