On de Sitter-like and Minkowski-like space-times
نویسندگان
چکیده
Friedrich’s proofs for the global existence results of de Sitter-like space-times and of semiglobal existence of Minkowski-like space-times [Comm. Math. Phys. 107, 587 (1986)] are re-examined and discussed, making use of the extended conformal field equations and a gauge based on conformal geodesics. In this gauge the location of the conformal boundary of the space-times is known a priori once the initial data has been prescribed. Thus it provides an analysis which is conceptually and calculationally simpler. PACS: 04.20.Ex, 04.20.Ha, 04.20.Gz

Spacelike hypersurfaces with constant $S$ or $K$ in de Sitter space or anti-de Sitter space
Let $M^n$ be an $n(ngeq 3)$-dimensional complete connected and oriented spacelike hypersurface in a de Sitter space or an anti-de Sitter space, $S$ and $K$ be the squared norm of the second fundamental form and Gauss-Kronecker curvature of $M^n$. If $S$ or $K$ is constant, nonzero and $M^n$ has two distinct principal curvatures one of which is simple, we obtain some charact...
متن کاملNonextreme and ultraextreme domain walls and their global space-times.
Non-extreme walls (bubbles with two insides) and ultra-extreme walls (bubbles of false vacuum decay) are discussed. Their respective energy densities are higher and lower than that of the corresponding extreme (supersymmetric), planar domain wall. These singularity free space-times exhibit non-trivial causal structure analogous to certain non-extreme black holes. We focus on anti-de Sitter– Min...
متن کاملDistinguishing de Sitter universe from thermal Minkowski spacetime by Casimir-Polder-like force
We demonstrate that the static ground state atom, which interacts with a conformally coupled massless scalar field in the de Sitter invariant vacuum, can obtain a position-dependent energy-level shift and this shift could cause a Casimir-Polder-like force on it. Interestingly no such force arises on the inertial atom bathed in a thermal radiation in the Minkowski universe. Thus, although the en...
متن کاملde Sitter Brane Gravity: from Close-Up to Panorama
We find explicitly the induced graviton propagator on de Sitter branes embedded in various five-dimensional spacetimes; de Sitter branes in AdS and Minkowski space are particular cases. By studying the structure of the momentum-space propagator, we are able to extract interesting physics, much of which is qualitatively different from that of flat branes. We find that 1) there can be a set of gr...
متن کاملOSp supergroup manifolds, superparticles and supertwistors
We construct simple twistor–like actions describing superparticles propagating on a coset superspace OSp(1|4)/SO(1, 3) (containing the D = 4 anti–de–Sitter space as a bosonic subspace), on a supergroup manifold OSp(1|4) and, generically, on OSp(1|2n). Making two different contractions of the superparticle model on the OSp(1|4) supermanifold we get massless superparticles in Minkowski superspace...
