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.

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 ...

Multivalued Mizoguchi-Takahashi type rational contraction in relational metric spaces [PDF]

Surveys in Mathematics and its Applications, 2023
In this paper we establish a result in the fixed point theory of multivalued mappings. This is done by combining three prevalent trends in fixed point theory. Some consequences of the main theorem are discussed.

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.

Aligning Metabolic Pathways Exploiting Binary Relation of Reactions. [PDF]

PLoS ONE, 2016
Metabolic pathway alignment has been widely used to find one-to-one and/or one-to-many reaction mappings to identify the alternative pathways that have similar functions through different sets of reactions, which has important applications in ...

Binary relations and reduced hypergroups

Discrete Mathematics, 2008
Let \(H\) be a nonempty set, \(\mathcal P(H)^*\) the family of nonempty subsets of \(H\) and \(\cdot\) a hyperoperation in \(H\), that is, \(\cdot\colon H\times H\to\mathcal P(H)^*\). J. Jantosciak defined three fundamental equivalence relations on any hypergroupoid \((H,\cdot)\) as follows: Let \(x,y\in H\), then (i) \(x\) and \(y\) are said to be ...

A note on two notions of compliance [PDF]

, 2014
We establish a relation between two models of contracts: binary session types, and a model based on event structures and game-theoretic notions. In particular, we show that compliance in session types corresponds to the existence of certain winning ...

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Relaxing the Φ-Family Auxiliary Functions and Related Results

Axioms
This article establishes the existence of fixed points and common fixed points for set-valued mappings satisfying an implicit-type contraction inequality involving a new auxiliary function in a complete metric space equipped with a binary relation ...
