A New Representation of Semiopenness of L-fuzzy Sets in RL-fuzzy Bitopological Spaces [PDF]
Symmetry, 2021 In this paper, we introduce a new representation of semiopenness of L-fuzzy sets in RL-fuzzy bitopological spaces based on the concept of pseudo-complement. The concepts of pairwise RL-fuzzy semicontinuous and pairwise RL-fuzzy irresolute functions are extended and discussed based on the (i,j)-RL-semiopen gradation.

ON FUZZY BITOPOLOGICAL SPACES IN ŠOSTAK'S SENSE (II)
Communications of the Korean Mathematical Society, 2010 In this paper, we used the supra fuzzy topology which generated from a fuzzy bitopological space (1) to introduce and study the concepts of continuity (resp. openness, closeness) of mapping, separation axioms and compactness for a fuzzy bitopo- logical spaces.

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 In this study, new operations of union, intersection, and complement are defined with the help of vague soft sets in a new way that is in both true and false statements, union is defined with maximum, and intersection is defined with minimum. On the basis of these operations, vague soft topology is defined.

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.

On Tri‐α‐Open Sets in Fuzzifying Tritopological Spaces
Advances in Fuzzy Systems, Volume 2019, Issue 1, 2019., 2019 In this paper, we introduced and studied (1,2,3)‐α‐open set, (1,2,3)‐α‐neighborhood system, (1,2,3)‐α‐derived, (1,2,3)‐α‐closure, (1,2,3)‐α‐interior, (1,2,3)‐α‐exterior, (1,2,3)‐α‐boundary, (1,2,3)‐α‐convergence of nets, and (1,2,3)‐α‐convergence of filters in fuzzifying tritopological spaces.

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 Lower Separation and Regularity Axioms in Fuzzy Topological Spaces
Advances in Fuzzy Systems, Volume 2011, Issue 1, 2011., 2011 We use the concepts of the quasicoincident relation to introduce and investigate some lower separation axioms such as αT0, αT1, αT1/2, and αT2 as well as the regularity axioms αR0 and αR1. Further we study some of their properties and the relations among them in the general framework of fuzzy topological spaces.

Intuitionistic Fuzzy Supra Bitopological Spaces [PDF]
, 2021 Abstract In this paper we will introduce the concept of intuitionistic fuzzy supra bitopological spaces and study the fundamental properties of intuitionistic fuzzy supra bitopological spaces. Also introduce intuitionistic fuzzy supra bi-continuous functions in intuitionistic fuzzy supra bitopological spaces.

Sobriety and Localic Compactness in Categories of L‐Bitopological Spaces
International Journal of Mathematics and Mathematical Sciences, Volume 2007, Issue 1, 2007., 2007 The notions of L‐sobriety and L‐spatiality are introduced for the category L‐BiTop of L‐bitopological spaces. Such notions are used to extend the known adjunction between the category L‐Top of L‐topological spaces and the category Loc of locals to one between the category L‐BiTop and BiLoc.
