Some Properties of (1, 2)*‐Locally Closed Sets
International Journal of Analysis, Volume 2014, Issue 1, 2014., 2014 A new kind of generalization of (1, 2)*‐closed set, namely, (1, 2)*‐locally closed set, is introduced and using (1, 2)*‐locally closed sets we study the concept of (1, 2)*‐LC‐continuity in bitopological space. Also we study (1, 2)*‐contracontinuity and lastly investigate its relationship with (1, 2)*‐LC‐continuity.

On T0 fuzzy Bitopological spaces
Journal of Bangladesh Academy of Sciences, 2014 In this paper, the authors introduced two notions of fuzzy pairwise-T0 bitopological spaces and compared them with other such concepts. The authors also studied some other properties of these spaces. DOI: http://dx.doi.org/10.3329/jbas.v38i2.21345 Journal of Bangladesh Academy of Sciences, Vol. 38, No.

AIMS Mathematics<p>A topological space $ \left(X, \tau \right) $ is called a $ KC $-space when every compact subset of $ X $ is closed. The aim of this paper is to introduce new, namely $ KC $-bitopological spaces and pairwise $ KC $-topological spaces "$ P $-$ KC $-topological spaces".

On ℳ𝒜(i,j)‐Continuous Functions in Biminimal Structure Spaces
International Journal of Mathematics and Mathematical Sciences, Volume 2013, Issue 1, 2013., 2013 We introduce the notion of ℳ𝒜(i,j)‐continuous functions and some other forms of continuity in biminimal structure spaces. Some new characterizations and several fundamental properties of ℳ𝒜(i,j)‐continuous functions are obtained.

Lattice‐Valued Topological Systems as a Framework for Lattice‐Valued Formal Concept Analysis
Journal of Mathematics, Volume 2013, Issue 1, 2013., 2013 Recently, Denniston, Melton, and Rodabaugh presented a new categorical outlook on a certain lattice‐valued extension of Formal Concept Analysis (FCA) of Ganter and Wille; their outlook was based on the notion of lattice‐valued interchange system and a category of Galois connections. This paper extends the approach of Denniston et al.

ON SOME BITOPOLOGICAL SEPARATION AXIOMS
Journal of New Theory, 2016 Abstaract−Fletcher et al. [1] introduced the concept of pairwise compactness for bitopological spaces. Reilly extended this concept to a larger class of bitopological spaces, called pairwise Lindel¨of spaces.

Properties of Separation Axioms in Bitopological Spaces
Journal of Bangladesh Academy of Sciences, 2020 In this paper, three notions of separation axioms in bitopological space are discussed. Some relations of topology and bitopology in such notions have been found. Further, that these notions are hereditary and topological property are proved.

On fuzzy b-locally open sets in bitopological spaces [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2015 In this article we introduce the notion of fuzzy b-locally open (bLO) sets, fuzzy bLO* sets, fuzzy bLO** sets in fuzzy bitopological spaces and obtain several characterizations and some properties of these sets.

Characterizations of Quasi-Metrizable Bitopological Spaces [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1988 AbstractIn this paper we prove that a pairwise Hausdorff bitopological space is quasi-metrizable if and only if for each point x ∈ X and for i, j = 1,2, i ≠ j, one can assign nbd bases { S(n, i; x) | n = 1, 2,… } such that (i) y ∉ S (n − 1, i; x) imples S(n, i; x) ∩ S (n, j; y) = φ, (ii) y ∈ S (n, i; x) implies S (n, i; y) ⊂ S(n − 1, i; x). We derive
