Topological pair
text:
In mathematics, more specifically algebraic topology, a pair is shorthand for an inclusion of topological spaces i : A ↪ X . Sometimes i is assumed to be a cofibration. A morphism from to is given by two maps f : X → X ′ and g : A → A ′ such that i ′ ∘ g = f ∘ i . A pair of spaces is an ordered pair where X is a topological space and A a subspace. The use of pairs of spaces is sometimes more convenient and technically superior to taking a quotient space of X by A. Pairs of spaces occur centrally
