Définition(s)
-
In mathematics, a γ-space is a topological space that satisfies a certain a basic selection principle. An infinite cover of a topological space is an ω-cover if every finite subset of this space is contained in some member of the cover, and the whole space is not a member the cover. A cover of a topological space is a γ-cover if every point of this space belongs to all but finitely many members of this cover. A γ-space is a space in which every open ω-cover contains a γ-cover.
