See all on Wikipediahttps://en.wikipedia.org/wiki/Binary_relationIn mathematics, a binary relation associates elements of one set, called the domain, with elements of another set, called the codomain. A binary relation over sets X and Y is a new set of ordered pairs (x, y) consisting of elements x in X and y in Y. It is a generalization of the more widely understood idea

In mathematics, a binary operation or dyadic operation is a rule for combining two elements to produce another element. More formally, a binary operation is an operation of arity two. More specifically, a binary operation on a set is an operation whose two domains and the codomain are the same set. Examples include the familiar arithmetic operations of addition, subtraction, and …

Binary relation - Wikipedia, the free encyclopedia
https://www.classicistranieri.com/en/articles/b/i/n/Binary_relation.htmlIn mathematics, a binary relation (or a dyadic or 2-place relation) is an arbitrary association of elements within a set or with elements of another set. An example is the " divides " relation between the set of prime numbers P and the set of integers Z , in which every prime p is associated with every integer z that is a multiple of p , but no other.

From Wikipedia, the free encyclopedia In mathematics, a homogeneous relation (also called endorelation) over a set X is a binary relation over X and itself, i.e. it is a subset of the Cartesian product X × X. This is commonly phrased as "a relation on X " or "a (binary) relation over X ".
