Coupled fixed point sets with data-dependence and stability [PDF]
Surveys in Mathematics and its Applications, 2022 In this paper we establish a coupled fixed point theorem of a coupled multivalued mapping defined on a complete metric space. In our result we use a new contractive inequality. There are rational terms in the expression of the inequality. The contractive

On the properties of contact binary stars
, 2004 A catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968a,b)

AIMS Mathematics, 2020 In this paper, we introduce a new implicit function without any continuity requirement and utilize the same to prove unified relation-theoretic fixed point results. We adopt some examples to exhibit the utility of our implicit function.

Perov Fixed-Point Results on F-Contraction Mappings Equipped with Binary Relation
Mathematics, 2023 The purpose of this article is to discuss some new aspects of the vector-valued metric space. The idea of an arbitrary binary relation along with the well-known F contraction is used to demonstrate the existence of fixed points in the context of a ...

Binary relations in the space of binary relations. I.
Applied Mathematical Sciences, 2014 This article formulates principles of extension, saturation and convergence, and shows how to implement them. In socio-economic systems, there are "reference groups", with the indicators of which the results of the research and experimentation are compared.

Binary and ternary relations [PDF]
Mathematica Bohemica, 1992 Let \(G\) be a set, \(\rho\) a binary relation on \(G\). Further, let \(r\) be a binary relation on the set \(\rho\) with the property \(\alpha=(x,y)\in\rho\), \(\beta=(z,u)\in\rho\), \((\alpha,\beta)\in r\Rightarrow y=z\). Then \(r\) is called a binding relation on \(\rho\), and \((G,\rho,r)\) is called a double binary structure.

Relation-Theoretic Contraction Principle In Metric Spaces Using Multiplicative Contraction
Ratio Mathematica, 2023 Alam and Imdad have presented a novel application of the Banach contraction principle on a complete metric spaces with a binary relation. We have extended the concept of binary relation with the multiplicative contraction in a complete metric spaces.

Compressed Dynamic Binary Relations [PDF]
2012 Data Compression Conference, 2012 We introduce a dynamic data structure for the compact representation of binary relations R ? A × B. Apart from checking whether two objects (a, b) ? A × B are related, and listing the objects of B related to some a ? A and vice versa, the structure allows inserting and deleting pairs (a, b) in the relation, as well as modifying the base sets A and B ...

Measuring the neutron star tidal deformability with equation-of-state-independent relations and gravitational waves [PDF]
, 2018 Gravitational wave measurements of binary neutron star coalescences offer information about the properties of the extreme matter that comprises the stars. Despite our expectation that all neutron stars in the Universe obey the same equation of state, i.e.
