Approximations of pythagorean fuzzy sets over dual universes by soft binary relations

Journal of Intelligent & Fuzzy Systems, 2021
 Yager introduced the Pythagorean Fuzzy Set (PFS) to deal with uncertainty in real-world decision-making problems. Binary relations play an important role in mathematics as well as in information sciences.

A Simple Parallel Algorithm for Natural Joins on Binary Relations

International Conference on Database Theory, 2020
In PODS'17, Ketsman and Suciu gave an algorithm in the MPC model for computing the result of any natural join where every input relation has two attributes.

The mathematics of xenology: di-cographs, symbolic ultrametrics, 2-structures and tree-representable systems of binary relations

Journal of Mathematical Biology, 2016
The concepts of orthology, paralogy, and xenology play a key role in molecular evolution. Orthology and paralogy distinguish whether a pair of genes originated by speciation or duplication.

The clone relation of a binary relation

Information Sciences, 2017
Abstract In a recent paper, De Baets et al. introduced the clone relation of a strict order relation. Two elements of a poset are said to be a pair of clones (or to be clones) if every other element that is greater (resp. smaller) than one of them is also greater (resp. smaller) than the other one.

Hypergroups and binary relations

Algebra Universalis, 2000
The paper deals with a binary relation R on a set H, where the Rosenberg partial hypergroupoid H R is a hypergroup. It proves that if H R is a hypergroup, S is an extension of R contained in the transitive closure of R and
