Fuzzy $e$-regular spaces and strongly $e$-irresolute mappings [PDF]
Sahand Communications in Mathematical Analysis, 2018 The aim of this paper is to introduce fuzzy ($e$, almost) $e^{*}$-regular spaces in $check{S}$ostak's fuzzy topological spaces. Using the $r$-fuzzy $e$-closed sets, we define $r$-($r$-$theta$-, $r$-$etheta$-) $e$-cluster points and their properties ...

Journal of Mathematical Analysis and Applications, 1984 The authors define fuzzy \(T_ 1\)-topological spaces (X,\(\tau)\) using fuzzy points introduced by \textit{C. K. Wong} [ibid. 46, 316-328 (1974; Zbl 0278.54004)]. \(T_ 1\)-ness is defined as weak separation by fuzzy open sets. The main theorem shows a difference to the topological analogue.

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...

Convergence in topological spaces [PDF]
, 1970 This paper will show the inadequacy of sequences to define certain concepts in topological spaces as fundamental as the real numbers. It introduces a generalization of a sequence, called a net, and shows that with nets it is possible to overcome this ...

British Educational Research Journal, EarlyView.Abstract In this paper, we explore how neurodivergent ways of being in early education are often gendered. The intersectionalities of gender and neurodivergence often lead to fixed expectations that perpetuate binary interpretations, pathologisations, missed diagnoses and a lack of curated support.

On fuzzy T1-topological spaces
Journal of Mathematical Analysis and Applications, 1988 In literature there appear at least two ways to generalize the topological \(T_ 1\)-axioms to fuzzy topological spaces: a fuzzy topological space X is a fuzzy \(T_ 1\)-space if (a) for any two distinct points \(p,q\in X\) there exist open sets U, V such that \(p\in U\), \(q\not\in U\), \(q\in V\), \(p\not\in V\), or (b) all singletons are fuzzy closed.

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

A Review of Fuzzy Soft Topological Spaces, Intuitionistic Fuzzy Soft Topological Spaces and Neutrosophic Soft Topological Spaces [PDF]

On Doitchinov's quietness for arbitrary quasi-uniform spaces [PDF]
, 2010 The notion of a quiet quasi-uniform space was introduced by Doitchinov in1988 when he developed an interesting completion theory for this class ofquasi-uniform spaces.

A fuzzification of the category of M-valued L-topological spaces
Applied General Topology, 2004 A fuzzy category is a certain superstructure over an ordinary category in which ”potential” objects and ”potential” morphisms could be such to a certain degree. The aim of this paper is to introduce a fuzzy category FTOP(L,M) extending the category TOP(L,
