Mathematics, 2022 In this paper, we obtain the results of coincidence and common fixed points in b-metric spaces. We work with a new type of multivalued quasi-contractive mapping with nonlinear comparison functions.

Fuzzy pairwise regular bitopological spaces in quasi-coincidence sense
Journal of Bangladesh Academy of Sciences, 2021 This paper introduces three notions of fuzzy pairwise regular between bitopological spaces in quasi-coincidence sense. Then, we investigate some relations between ours and other counterparts. We observe that all these concepts are preserved under one-one, onto, fuzzy closed, fuzzy open, and fuzzy continuous mappings.

The origin of the period-$2T/7$ quasi-breathing in disk-shaped Gross-Pitaevskii breathers
SciPost Physics, 2022 We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where the quasi-period $T_{\text{quasi-breathing}}\sim$~$2T/7$ and $T$ is the ...

Weak proximal normal structure and coincidence quasi-best proximity points
Applied General Topology, 2020 We introduce the notion of pointwise cyclic-noncyclic relatively nonexpansive pairs involving orbits. We study the best proximity point problem for this class of mappings.

Characterizations of Ordered Semigroups by New Type of Interval Valued Fuzzy Quasi-Ideals
Journal of Applied Mathematics, 2014 The concept of non-k-quasi-coincidence of an interval valued ordered fuzzy point with an interval valued fuzzy set is considered. In fact, this concept is a generalized concept of the non-k-quasi-coincidence of a fuzzy point with a fuzzy set.

An in-depth exploration of intuitionistic fuzzy T₀ in the context of bitopology [PDF]
Notes on IFSIntuitionistic fuzzy topological space and bitopological space have been introduced by using the concepts of intuitionistic fuzzy sets which are the generalizations of interval valued fuzzy sets.

Mappings in Fuzzy Hausdorff Spaces in Quasi-Coincidence Sense
Journal of Bangladesh Academy of Sciences, 2017 In this paper, we introduce two notions of T2 property in fuzzy topological spaces by using quasi-coincidence sense and we establish relationship among our and other such notions. We also show that all these notions satisfy good extension property. Also hereditary, productive and projective properties are satisfied by these notions. We observe that all

Symmetry Conditions on the Coincidence of Some Notions of Quasi-Uniform Completeness
International Journal of Mathematics and Mathematical Sciences, 2007 We generalize the notions of quietness and semisymmetry defined by Doitchinov (1991) and Deák (1991) and we study the role of these extended notions on the coincidence of some well-known quasi-uniform completeness.

Fuzzy Normal Topological Space in Quasi-Coincidence Sense
Journal of Bangladesh Academy of Sciences, 2018 Three notions of normal property in fuzzy topological spaces using quasi-coincidence sense are introduced in this paper and relationship among these and other such notions are established. It is also shown that all these notions satisfy ‘good extension’ property.

On Topological Structures of Fuzzy Parametrized Soft Sets
The Scientific World Journal, 2014 We introduce the topological structure of fuzzy parametrized soft sets and fuzzy parametrized soft mappings. We define the notion of quasi-coincidence for fuzzy parametrized soft sets and investigated its basic properties. We study the closure, interior,
