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 versus non-binary information in real time series: empirical results and maximum-entropy matrix models [PDF]
New Journal of Physics, 2014 The dynamics of complex systems, from financial markets to the brain, can be monitored in terms of multiple time series of activity of the constituent units, such as stocks or neurons, respectively.

Binary Relations as a Foundation of Mathematics [PDF]
, 2007 We describe a theory for binary relations in the Zermelo-Fraenkel style. We choose for ZFCU, a variant of ZFC Set theory in which the Axiom of Foundation is replaced by an axiom allowing for non-wellfounded sets.

Aggregating Fuzzy Binary Relations and Fuzzy Filters
Discussiones Mathematicae - General Algebra and Applications, 2018 The main goal of this paper is to investigate the aggregation of diverse families of binary fuzzy relations, fuzzy filters, and fuzzy lattices. Some links between these families and their images via an aggregation are explored.

Mathematics, 2023 This article consists of some new fixed point theorems verifying relation-theoretic strict almost nonlinear contractions that are preserved by a locally finitely transitive relation. Our results improve certain well-known results in the literature.

Almost Contractions under Binary Relations
Axioms, 2022 After the introduction of almost contraction due to Berinde, the branch of metric fixed point theory has attracted much attention in this direction, and various fixed point results have been proved for almost contractions via different approaches.

A Relation-Theoretic Matkowski-Type Theorem in Symmetric Spaces
Axioms, 2021 In this paper, we present a fixed-point theorem in R-complete regular symmetric spaces endowed with a locally T-transitive binary relation R using comparison functions that generalizes several relevant existing results.

Relation-theoretic almost ϕ-contractions with an application to elastic beam equations
AIMS Mathematics, 2023 In this article, we prove some results on existence and uniqueness of fixed points for an almost $ \phi $-contraction mapping defined on a metric space endowed with an amorphous relation.
