Some Results of τ1τ2-δ Semiconnectedness and Compactness in Bitopological Spaces
Journal of Mathematics, 2018 We are going to establish some results of τ1τ2-δ semiconnectedness and compactness in a bitopological space. Besides, we will investigate several results in τ1τ2-δ semiconnectedness for subsets in bitopological spaces.

On Cℵ-fibrations in bitopological semigroups. [PDF]
ScientificWorldJournal, 2014 We extend the path lifting property in homotopy theory for topological spaces to bitopological semigroups and we show and prove its role in the Cℵ‐fibration property. We give and prove the relationship between the Cℵ‐fibration property and an approximate fibration property. Furthermore, we study the pullback maps for Cℵ‐fibrations.

[Retracted] Neutrosophic Soft Quad Structures Concerning Neutrosophic Soft Points
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 In this article, a new concept of neutrosophic soft quad‐topological structures is introduced. Generalised neutrosophic soft ∗b open sets in neutrosophic soft quad‐topological structures concerning soft points of the space are introduced. Different results are addressed in neutrosophic soft quad‐topological structure on the basis of these new ...

Preopenness Degree in RL‐Fuzzy Bitopological Spaces
Abstract and Applied Analysis, Volume 2022, Issue 1, 2022., 2022 Based on the concept of pseudocomplement, we introduce a new representation of preopenness of L‐fuzzy sets in RL‐fuzzy bitopological spaces. The concepts of pairwise RL‐fuzzy precontinuous and pairwise RL‐fuzzy preirresolute functions are extended and discussed based on the (i, j)‐RL‐preopen gradation.

[Retracted] New Soft Structure: Infra Soft Topological Spaces
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 It is always convenient to find the weakest conditions that preserve some topologically inspired properties. To this end, we introduce the concept of an infra soft topology which is a collection of subsets that extend the concept of soft topology by dispensing with the postulate that the collection is closed under arbitrary unions.

Infra Soft Compact Spaces and Application to Fixed Point Theorem
Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021 Infra soft topology is one of the recent generalizations of soft topology which is closed under finite intersection. Herein, we contribute to this structure by presenting two kinds of soft covering properties, namely, infra soft compact and infra soft Lindelöf 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.

More on Selective Covering Properties in Bitopological Spaces
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 In this study, we continue our investigation of selective covering properties in bitopological spaces. We discuss their behaviour under certain kinds of mappings. We also introduce selective versions of the ccc property and the star‐ccc property in bitopological spaces and give few of their relations with other selective properties.

A New Closed Set in Topological Spaces
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 Our purpose of this work is to implement a class of sg∧‐closed sets, which is property placed among the classes of semiclosed sets and gs‐closed sets. The relations with other concepts directly or indirectly joined with generalized closed sets are inspected.

Compactness on Soft Topological Ordered Spaces and Its Application on the Information System
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 It is well known every soft topological space induced from soft information system is soft compact. In this study, we integrate between soft compactness and partially ordered set to introduce new types of soft compactness on the finite spaces and investigate their application on the information system. First, we initiate a notion of monotonic soft sets
