Projective bitopological spaces [PDF]
Journal of the Australian Mathematical Society, 1972 J. C. Kelly [2] introduced the concept of a bitopological space. Lane [3], Patty [4] and Pervin [5] have continued his work. Our purpose in this paper is to identify the projective objects in a suitable category of bitopological spaces after the manner of Gleason [1] and generalize his theorem that in the category of compact Hausdoriff topological ...

On 3-topological version of θ-regularity
International Journal of Mathematics and Mathematical Sciences, 2000 We modify the concept of θ-regularity for spaces with 2 and 3 topologies. The new, more general property is fully preserved by sums and products.

Some Subsets of Bitopological Spaces
International Journal of Analysis and Applications, 2023 In this paper, we introduce the notions of minimal u-ω-closed sets, maximal u-ω-open sets, u-ω-paraopen sets, u-ω-paraclosed sets, u-ω-mean open sets and u-ω-mean closed sets in bitopological spaces and obtain several characterizations and some of its ...

Pairwise locally compact and compactification in
Journal of Kufa for Mathematics and Computer, 2019 The concept of intuitionistic topological space was introduced by Çoker. The aim of this paper is to generalize notions between bitopological spaces and double topological spaces and also give a notion of pairwise locally compact and compactification ...

On Pairwise Semi-p-separation Axioms in Bitopological Spaces
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 In this paper, we define a new type of pairwise separation axioms called pairwise semi-p- separation axioms in bitopological spaces, also we study some properties of these spaces and relationships of each one with the ordinary separation axioms in the ...

On Some Generalized Open Sets in Ideal Bitopological Spaces
Journal of New Theory, 2020 In this article, we introduce and study the concepts of \gammaij- I -sets, \gammaij - preI -open sets, and \gammaij -b-I -open sets by generalizing (i,j)-I-open, (i,j)-preI-open, and (i,j)-bI- open sets, respectively, in ideal bitopological spaces with ...

Superextension as bitopological space
Izvestiya Instituta Matematiki i Informatiki. Udmurt. Gos. Univ., 2017 The author studies some properties of a bitopological space and its subspaces that appear on the superextension of a topological space \(X\). The superextension of \(X\) is the set of all maximal linked systems of closed subsets of \(X\). Two topologies on the superextension of \(X\) are considered: one of Wallman type and the other of Stone type.
