Partitioned binary relations [PDF]
Math. Scand. 113 (2013), no. 1, 30-52, 2011 We define the category of partitioned binary relations and show that it contains many classical diagram categories, including categories of binary relations, maps, injective maps, partitions, (oriented) Brauer diagrams and (oriented) Temperley-Lieb diagrams.

Mitsch's order and inclusion for binary relations and partitions [PDF]
, 2012 Mitsch's natural partial order on the semigroup of binary relations is here characterised by equations in the theory of relation algebras. The natural partial order has a complex relationship with the compatible partial order of inclusion, which is ...

Compact Binary Relation Representations with Rich Functionality [PDF]
arXiv, 2012 Binary relations are an important abstraction arising in many data representation problems. The data structures proposed so far to represent them support just a few basic operations required to fit one particular application.

Groups of Binary Operations and Binary $G$-Spaces [PDF]
Topology and its Applications, 201(2016), 18-28, 2023 The group of continuous binary operations on a topological space is studied; its relationship with the group of homeomorphisms is established. The category of binary $G$-spaces and bi-equivariant maps is constructed, which is a natural extension of the category of $G$-spaces and equivariant maps.

Selective Games on Binary Relations [PDF]
, 2014 We present a unified approach, based on dominating families in binary relations, for the study of topological properties defined in terms of selection principles and the games associated to them.Comment: 28 ...

Quasiuniversal properties of neutron star mergers [PDF]
, 2014 Binary neutron star mergers are studied using nonlinear 3+1 numerical relativity simulations and the analytical effective-one-body (EOB) model. The EOB model predicts quasiuniversal relations between the mass-rescaled gravitational wave frequency and the

Relative Expressive Power of Navigational Querying on Graphs [PDF]
, 2014 Motivated by both established and new applications, we study navigational query languages for graphs (binary relations). The simplest language has only the two operators union and composition, together with the identity relation.

Finding binary words with a given number of subsequences [PDF]
\.Zak R., Finding binary words with a given number of
subsequences, Theoretical Computer Science 919 (2022), pp. 75-79, 2022 We relate binary words with a given number of subsequences to continued fractions of rational numbers with a given denominator. We deduce that there are binary strings of length $O(\log n \log \log n)$ with exactly $n$ subsequences; this can be improved to $O(\log n)$ under assumption of Zaremba's conjecture.

Binary versus non-binary information in real time series: empirical results and maximum-entropy matrix models [PDF]
, 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.

The slope, the hill, the drop, and the swoosh: Learning about the nuclear matter equation of state from the binary Love relations [PDF]
, 2021 Analyses that connect astrophysical observations of neutron stars with nuclear matter properties sometimes rely on equation-of-state insensitive relations. We show that the slope of the binary Love relations (i.e.~between the tidal deformabilities of binary neutron stars) encodes the rate of change of the nuclear matter speed of sound below three times
