    Generalized closed sets: a unified approach 
    Cao, Jiling; Greenwood, Sina; Reilly, Ivan L. (Universitat Politècnica de València, 2001-10-01)
    [EN] We investigate various classes of generalized closed sets of a topological space in a unified way by studying the notion of qr-closed sets. New characterizations of some existing classes of generalized closed sets and ...

    On br -closed sets 
    Ganster, Maximilian; Steiner, Markus (Universitat Politècnica de València, 2007-10-01)
    [EN] This paper is closely related to the work of Cao, Greenwood and Reilly in as it expands and completes their fundamental diagram by considering b-closed sets. In addition, we correct a wrong assertion in about βgs-spaces.

    δ-closure, θ-closure and generalized closed sets 
    Cao, Jiling; Ganster, Maximilian; Reilly, Ivan L.; Steiner, Markus (Universitat Politècnica de València, 2005-04-01)
    [EN] We study some new classes of generalized closed sets (in the sense of N. Levine) in a topological space via the associated δ-closure and θ-closure. The relationships among these new classes and existing classes of ...
