Algebras of Binary Isolating Formulas for Tensor Product Theories

Известия Иркутского государственного университета: Серия "Математика", 2022
Algebras of distributions of binary isolating and semi-isolating formulae are derived objects for a given theory and reflect binary formula relations between 1-type realizations.

The gender-binary cycle: the perpetual relations between a biological-essentialist view of gender, gender ideology, and gender-labelling and sorting

Philosophical Transactions of the Royal Society of London. Biological Sciences, 2020
Gender inequality is one of the most pressing issues of our time. A core factor that feeds gender inequality is people's gender ideology—a set of beliefs about the proper order of society in terms of the roles women and men should fill.

A note on first-order spectra with binary relations [PDF]

Logical Methods in Computer Science, 2018
The spectrum of a first-order sentence is the set of the cardinalities of its finite models. In this paper, we consider the spectra of sentences over binary relations that use at least three variables.

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.

A Unified Framework for Generalized Symmetric Contractions and Economic Dynamics via Fractional Differential Equations

Fractal and Fractional
This study has developed a unified framework for modeling economic growth through Caputo fractional differential equations. The framework has established the existence and uniqueness of solutions by employing a generalized fixed-point approach.

Fixed Point Theorems for Nonexpansive Mappings under Binary Relations

Mathematics, 2021
In the present article, we establish relation-theoretic fixed point theorems in a Banach space, satisfying the Opial condition, using the R-Krasnoselskii sequence. We observe that graphical versions (Fixed Point Theory Appl.

Some fixed point theorems for (CAB)-contractive mappings and related results [PDF]

Mathematica Moravica, 2015
In this paper, we introduced the concept of (CAB)-contractive mappings and provide sufficient conditions for the existence and uniqueness of a fixed point for such class of generalized nonlinear contractive mappings in metric spaces and several ...

Relation-theoretic metrical coincidence and common fixed point theorems under nonlinear contractions

Applied General Topology, 2018
In this paper, we prove coincidence and common fixed points results under nonlinear contractions on a metric space equipped with an arbitrary binary relation.
