compactification hampakâneš Fr.: compactification 1) Math.: A process applied to topological spaces having
many dimensions to make them compact spaces. Compactification, n. from → compactify. |
conformal compactification hampakâneš-e hamdi Fr.: compactification conforme A mapping of an infinite → space-time onto a finite one that may make the far away parts of the former accessible to study. The technique invented by Penrose defines an equivalence class of → metrics, g_{ab} being equivalent to ĝ_{ab} = Ω^{2}g_{ab}, where Ω is a positive scalar function of the space-time that modifies the distance scale making the asymptotics of the physical metric accessible to study. → conformal; → compactification. |
