    On soft generalized closed sets in soft topological spaces
    (Asian Research Publishing Network (ARPN), 2013) Yüksel Ş.; Tozlu N.; Güzel Ergül Z.
    In this paper, we continue the study of soft generalized closed sets in a soft topological space introduced by Kannan [1]. Firstly, we give a representation of soft sets and soft topological spaces. Secondly, we investigate behavior relative to soft subspaces of soft generalized closed sets. We show that a soft generalized closed set in a soft compact (soft Lindelöf, soft countably compact) space is also soft compact. Then, we show that a soft compact set in a soft regular space is soft generalized closed and disjoint soft g-closed sets in a soft normal space generally cannot be separated by soft open sets. Finally, we investigate some properties of soft generalized open sets. © 2005 - 2013 JATIT & LLS. All rights reserved.

    On soft generalized preregular closed and open sets in soft topological spaces
    (Hikari Ltd., 2014) Ergül Z.G.; Yüksel Ş.; Tozlu N.
    In this paper, we define soft generalized preregular closed and open sets in soft topological spaces which are defined over an initial universe with a fixed set of parameters and we investigate some basic properties of these concepts. Also we discuss their relationships with different types of subsets of soft topological spaces with the help of counterexamples. © 2014 Zehra Güzel Ergül, Şaziye Yüksel and Naime Tozlu.

    Soft regular generalized closed sets in soft topological spaces
    (Hikari Ltd., 2014) Yüksel S.; Tozlu N.; Ergül Z.G.
    Many researchers defined some basic notions on soft topology and studied many properties. In this paper, we define soft regular generalized closed and open sets in soft topological spaces and studied their some properties. We introduce these concepts which are defined over an initial universe with a fixed set of parameters. We investigate behavior relative to union, intersection and soft subspaces of soft regular generalized closed sets. We show that every soft generalized closed set is soft regular generalized closed. Also, we investigate many basic properties of these concepts. 2014 Sa¸ziye Yüksel, Naime Tozlu and Zehra Güzel Ergül.
