On Intuitionistic Fuzzy Minimal Semi-preopen Set [PDF]
مجلة علوم ذي قار, 2019 In this paper, we introduce the concept of intuitionistic fuzzy minimal open sets on intuitionistic fuzzy topological space. We introduce the concepts of closure and interior defined by intuitionistic fuzzy minimal open set and intuitionistic fuzzy ...

Characterizations of Strongly Compact Spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 2009 A topological space (X,τ) is said to be strongly compact if every preopen cover of (X,τ) admits a finite subcover. In this paper, we introduce a new class of sets called -preopen sets which is weaker than both open sets and -open sets.

[Retracted] Characterization of Bipolar Vague Soft S‐Open Sets
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 This paper concerns the study of the concept of bipolar vague soft s‐open set, bipolar vague soft s‐interior, bipolar vague soft s‐closer, and bipolar vague soft s‐exterior in bipolar vague soft topological spaces. By using such concepts, some results are addressed in bipolar vague soft topological spaces.

[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 ...

Pythagorean Nanogeneralized Closed Sets with Application in Decision‐Making
Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021 Topology is studying the objects which are considered to be equal if they may also be continually deformed through other shapes as bending and twisting without tearing or glueing them. Topology is similar in geometrical structures and quantitatively equivalent. Nanotopology is the study of set.

[Retracted] On Strongly b−θ‐Continuous Mappings in Fuzzifying Topology
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 In this article, we will define the new notions (e.g., b − θ‐neighborhood system of point, b − θ‐closure (interior) of a set, and b − θ‐closed (open) set) based on fuzzy logic (i.e., fuzzifying topology). Then, we will explain the interesting properties of the above five notions in detail.

Some Applications of Supra Preopen Sets
Journal of Mathematics, 2020 The aim of this work is to define some concepts on supra topological spaces using supra preopen sets and investigate main properties. We started this paper by correcting some results obtained in previous study and presenting further properties of supra ...

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.
