A topological space $Y$ in which the given topological space $X$ is an everywhere-dense subspace. If $Y$ is compact, then it is called a compact extension, and if $Y$ is Hausdorff, it is called a Hausdorff extension.
Comments
Compact extensions are also called compactifications, cf. also Compactification.
