Knowledge Hypergraphs: Prediction Beyond Binary Relations
Knowledge graphs store facts using relations between two entities. In this work, we address the question of link prediction in knowledge hypergraphs where relations are defined on any number of entities.

Groups and Algebras of Binary Relations [PDF]
AbstractIn 1941, Tarski published an abstract, finitely axiomatized version of the theory of binary relations, called the theory of relation algebras. He asked whether every model of his abstract theory could be represented as a concrete algebra of binary relations.

A novel pessimistic multigranulation roughness by soft relations over dual universe
A multigranulation rough set over two universes delivers a unique perspective on the combination of multigranulation information. This paper presents the pessimistic multignualtion rough set over dual universes based on soft binary relations.

Nonlinear contractions in metric spaces under locally $T$-transitive binary relations [PDF]
In this paper, we present a variant of Boyd-Wong fixed point theorem in a metric space equipped with a locally T-transitive binary relation, which under universal relation reduces to Boyd-Wong (Proc. Amer. Math. Soc.

It was shown in [3] that every finite group is the maximal subgroup of a semigroupBx of all binary relations on some finite set X. This result is extended here to arbitrary groups.

Identities for field extensions generalizing the Ohno-Nakagawa relations [PDF]
In previous work, Ohno conjectured, and Nakagawa proved, relations between the counting functions of certain cubic fields. These relations may be viewed as complements to the Scholz reflection principle, and Ohno and Nakagawa deduced them as consequences

Dynamics on Binary Relations over Topological Spaces
The existence of chaos and the quest of dense orbits have been recently considered for dynamical systems given by multivalued linear operators. We consider the notions of topological transitivity, topologically mixing property, hypercyclicity, periodic ...

X-Ray Binary Luminosity Function Scaling Relations for Local Galaxies Based on Subgalactic Modeling [PDF]
We present new Chandra constraints on the X-ray luminosity functions (XLFs) of X-ray binary (XRB) populations, as well as their scaling relations, for a sample of 38 nearby galaxies (D = 3.4–29 Mpc).

Ordinal notions of submodularity [PDF]
We consider several ordinal formulations of submodularity, defined for arbitrary binary relations on lattices. Two of these formulations are essentially due to Kreps [Kreps, D.M., 1979.
