    Extensions of closure spaces 
    Deses, D.; de Groot-Van der Voorde, A.; Lowen-Colebunders, E. (Universitat Politècnica de València, 2003-10-01)
    [EN] A closure space X is a set endowed with a closure operator P(X) → P(X), satisfying the usual topological axioms, except finite additivity. A T1 closure extension Y of a closure space X induces a structure ϒ on X ...

    On complete objects in the category of T0 closure spaces 
    Deses, D.; Giuli, Eraldo; Lowen-Colebunders, E. (Universitat Politècnica de València, 2003-04-01)
    [EN] In this paper we present an example in the setting of closure spaces that fits in the general theory on “complete objects” as developed by G. C. L. Brümmer and E. Giuli. For V the class of epimorphic embeddings in the ...

    The quasitopos hull of the construct of closure spaces 
    Claes, Veerle; Sonck, G. (Universitat Politècnica de València, 2003-04-01)
    [EN] In the list of convenience properties for topological constructs the property of being a quasitopos is one of the most interesting ones for investigations in function spaces, differential calculus, functional analysis, ...
