    ON GENERALIZED PRE-CLOSURE SPACES AND SEPARATION FOR SOME SPECIAL TYPES OF FUNCTIONS
    (Forum Editrice Univ Udinese, 2010) Caldas, Miguel; Ekici, Erdal; Jafari, Saeid
    In this paper, we show that a pointwise symmetric pre -isotonic pre -closure functions is uniquely determined by the pairs of sets it separates. We then show that when the pre -closure function of the domain is pre -isotonic and the pre -closure function of the codomain is pre -isotonic and pointwise-pre-symmetric, functions which separate only those pairs of sets which are already separated are pre -continuous.

    On weakly BR-closed functions between topological spaces
    (Univ Osijek, Dept Mathematics, 2009) Caldas, Miguel; Ekici, Erdal; Jafari, Saeid; Moshokoa, Seithuti P.
    In this paper, we offer a new class of functions called weakly BR-closed functions. Moreover, we investigate not only some of their basic properties but also their relationships with other types of already well-known functions.

    Slightly γ-Continuous Functions
    (2004) Ekici, Erdal; Caldas, Miguel
    The purpose of this paper is to give a new weak form of some types of continuity generalizing strongly γ-irresoluteness, γ-irresoluteness, γ-continuity, precontinuity, semi-continuity, γ-continuity and slightly continuity. In this paper, slightly γ-continuity is introduced and studied. Furthermore, basic properties and preservation theorems of slightly γ-continuous functions are investigated and relationships between slightly γ-continuous functions and graphs are investigated. © SPM.
