On topological structures of fuzzy parametrized soft sets [PDF]
, 2014 In this paper, we introduce the topological structure of fuzzy parametrized soft sets and fuzzy parametrized soft mappings. We define the notion of quasi-coincidence for fuzzy parametrized soft sets and investigated basic properties of it.

Paracompactness with respect to an ideal
International Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 3, Page 433-442, 1997., 1995 An ideal on a set X is a nonempty collection of subsets of X closed under the operations of subset and finite union. Given a topological space X and an ideal ℐ of subsets of X, X is defined to be ℐ‐paracompact if every open cover of the space admits a locally finite open refinement which is a cover for all of X except for a set in ℐ.

, 2007 Basic properties of cl-supercontinuity, a strong variant of continuity, due to Reilly and Vamanamurthy [Indian J. Pure Appl. Math., 14 (1983), 767–772], who call such maps clopen continuous, are studied.

Application on local discrete expansion
International Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 4, Page 747-750, 1996., 1995 The process of changing a topology by some types of its local discrete expansion preserves s‐closeness, S‐closeness, semi‐compactness, semi‐Ti, semi‐Ri, i ∈ {0, 1, 2}, and extremely disconnectness. Via some other forms of such above replacements one can have topologies which satisfy separation axioms the original topology does not have.

On star Rothberger spaces modulo an ideal
Applied General TopologyIn this article, we introduce the ideal star-Rothberger property by coupling the notion of a star operator to that of an ideal Rothberger space, after which some of its topological characteristics are analysed. By creating relationships between a numbers

, 2004 We present an example of a compact connected F-space with a continuous real-valued function f for which the union of the interiors of its fibers is not dense.

SOME PROPERTIES OF $\alpha$-OPEN SETS WITH RESPECT TO AN IDEAL
, 2015 The aim of this paper is to introduce some types of compactness and connectedness in ideal topological spaces. We further study some properties of these types.

Perfect maps in compact (countably compact) spaces
International Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 4, Page 773-776, 1995., 1993 In this paper, among other results, characterizations of perfect maps in compact Hausdorff(Fréchet, countably compact, Hausdorff) spaces are obtained.

COMPACT SPACES WITH RESPECT TO AN IDEAL
, 2014 The aim of this paper is to study compactness modulo an ideal called I-compact spaces and discuss their properties. Some of the results in compact spaces have been generalized in terms of I-compact spaces.

Measures of Lindelof and separability in approach spaces
International Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 3, Page 597-606, 1994., 1993 In this paper we introduce the notions of separability and Lindelöf in approach spaces and investigate their behaviour under products and subspaces.
