On Fuzzy C-Paracompact Topological Spaces [PDF]
Mathematics, 2022 The aim of this paper is to study fuzzy extensions of some covering properties defined by A. V. Arhangel’skii and studied by other authors. Indeed, in 2016, A. V.

Regularity and Paracompactness in Fuzzy Topological Spaces
International Journal of Analysis and Applications, 2023 In this paper we obtain two characterizations of regular fuzzy topological spaces using Luo's and Abd El-Monsef and others' paracompact fuzzy topological spaces.

On some paracompactness-type properties of fuzzy topological spaces [PDF]
AIP Conference Proceedings, 2019 The aim of this paper is to study some paracompactness-type properties for fuzzy topological spaces. We prove that these properties are good extensions of others defined by A.V. Arkhangel’skii (and studied by S.A. Peregudov) and obtain several results about them.

On the goodness of some types of fuzzy paracompactness in Sostak's fuzzy topology [PDF]
International Journal of Fuzzy Logic and Intelligent Systems, 2005 We introduce in Sostak’s fuzzy topological spaces definitions of paracompactness, almost paracompactness, and near paracompactness all of which turn to be good extensions of their classical topological counterparts. Fuzzy semi-paracompact, para S-closed and weakly paracompact spaces are treated to a similar approach.

Paracompactness in fuzzy topological spaces
Journal of Mathematical Analysis and Applications, 1988 This paper introduces two different types of paracompactness in the setting of fuzzy spaces, both of which are good extensions and have pleasing properties.

Difference Lindelöf Perfect Function in Topology and Statistical Modeling
MathematicsWe develop the theory of Difference Lindelöf perfect functions. Through difference covers, we provide intrinsic characterizations; prove stability under composition, subspace restriction, and suitable products; and obtain preservation theorems.

Complete Hausdorffness and Complete Regularity on Supra Topological Spaces
Journal of Applied Mathematics, Volume 2021, Issue 1, 2021., 2021 The supra topological topic is of great importance in preserving some topological properties under conditions weaker than topology and constructing a suitable framework to describe many real‐life problems. Herein, we introduce the version of complete Hausdorffness and complete regularity on supra topological spaces and discuss their fundamental ...

Soft ω*-Paracompactness in Soft Topological Spaces
International Journal of Fuzzy Logic and Intelligent Systems, 2021 In this study, we introduce a new concept in soft topological spaces, namely, soft ω ∗ paracompactness, and we provide characterizations thereof. Its connection with other related concepts is also studied.

Journal of Mathematics, Volume 2020, Issue 1, 2020., 2020 In this paper, we define a weak type of soft Menger spaces, namely, nearly soft Menger spaces. We give their complete description using soft s‐regular open covers and prove that they coincide with soft Menger spaces in the class of soft regular ⋆ spaces.

Fuzzy Ideal Supra Topological Spaces
Advances in Fuzzy Systems, Volume 2020, Issue 1, 2020., 2020 In this paper, we introduce the notion of fuzzy ideals in fuzzy supra topological spaces. The concept of a fuzzy s‐local function is also introduced here by utilizing the s‐neighbourhood structure for a fuzzy supra topological space. These concepts are discussed with a view to find new fuzzy supra topologies from the original one.
