Covering relation information

mathematics, especially order theory, the covering relation of a partially ordered set is the binary relation which holds between comparable elements that...

In topology, a covering or covering projection is a map between topological spaces that, intuitively, locally acts like a projection of multiple copies...

reachability relation as the DAG. It has an edge u → v for every pair of vertices (u, v) in the covering relation of the reachability relation ≤ of the DAG...

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...

sets whose union contains each set as a subset Cover, a pair in the covering relation of a partially ordered set, or the greater element in such a pair...

order, if x < y then ρ(x) < ρ(y), and The rank is consistent with the covering relation of the ordering, meaning that for all x and y, if y covers x then...

partial cube of moves on weak orderings is the graph describing the covering relation of the face lattice of the permutohedron. For instance, for n = 3...

and join-irreducible elements. If a lattice is distributive, its covering relation forms a median graph. Furthermore, every distributive lattice is also...

binary relation is the relation that occurs when the order of the elements is switched in the relation. For example, the converse of the relation 'child of'...

In mathematics, a relation on a set is called connected or complete or total if it relates (or "compares") all distinct pairs of elements of the set in...

In mathematics, a binary relation R ⊆ X×Y between two sets X and Y is total (or left total) if the source set X equals the domain {x : there is a y with...

Christian head covering, also known as Christian veiling, is the traditional practice of women covering their head in a variety of Christian denominations...

which any two elements are comparable. That is, a total order is a binary relation ≤ {\displaystyle \leq } on some set X {\displaystyle X} , which satisfies...

pair is comparable. Formally, a partial order is a homogeneous binary relation that is reflexive, antisymmetric, and transitive. A partially ordered set...
