L-pre- and L-semi-P- compact Spaces

مجلة بغداد للعلوم, 2011
The purpose of this paper is to study a new types of compactness in the dual bitopological spaces. We shall introduce the concepts of L-pre- compactness and L-semi-P- compactness .

Soft Bitopological Spaces

International Journal of Computer Applications, 2014
In this paper, introduce and study the concept of soft bitopological spaces which are defined over an initial universe with a fixed set of parameters. Also introduce and investigate some new separation axioms called pairwise soft T0, pairwise soft T1 and pairwise soft T2 spaces and study some of their basic properties in soft bitopological spaces.

Some Types of Compactness in Bitopological Spaces

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
  In this paper, we give the concept of N-open set in bitopological spaces, where N is the first letter of the name of one of the authors, then we used this concept to define a new kind of compactness, namely N-compactness and we define the N-continuous

On pairwise super continuous mappings in bitopological spaces

International Journal of Mathematics and Mathematical Sciences, 1991
The aim of this paper is to define and study super-continuous mappings and some other forms of continuity such as strong continuity, perfect continuity and complete continuity in bitopological spaces and investigate the relations between these kinds of ...

GENERALIZED SEPARATION AXIOMS IN BITOPOLOGICAL SPACES

, 2008
O.A. El-Tantawy and H.M. Abu-Donia In this paper we introduce some classes of sets in a bitopological space (X, τ 1, τ 2). We show that some of these classes are infra topologies and some are supra topologies.

Semi-sequentially normal bitopological spaces

, 1992
In this paper we introduce a weak form of full normality for bitopological spaces, and consider its relationship to pairwise paracompactness in the sense of S. Romaguerra and J.

Bitopological spaces: theory, relations with generalized algebraic structures and applications

, 2005
This monograph is the first and an initial introduction to the theory of bitopological spaces and its applications. In particular, different families of subsets of bitopological spaces are introduced and various relations between two topologies are ...
