Holography and the Future Tube
Abstract
The Future Tube T+n of n-dimensional Minkowski spacetime may be identified with the reduced phase space or "space of motions" of a particle moving in (n+1)-dimensional Anti-de-Sitter spacetime. Both are isomorphic to a bounded homogeneous domain in Cn whose Shilov boundary may be identified with n-dimensional conformally compactified Minkowski spacetime.
