Divergence equations and uniqueness theorem of static spacetimes with conformal scalar hair

Takeshi Shinohara et al.

Summary: Researchers reexamined the Israel-type proof of the uniqueness theorem for the static spacetime outside the photon surface in the Einstein-conformal scalar system, deriving a new divergence identity with three parameters that played a key role in providing a new proof of uniqueness.

Static spacetimes haunted by a phantom scalar field. I. Classification and global structure in the massless case

Cristian Martinez et al.

Summary: Novel features of n-dimensional spacetimes sourced by a massless (non) phantom scalar field in general relativity are discussed, including a complete classification of static solutions and the existence of parallelly propagated curvature singularities. The study also reveals the presence of regular wormholes in two-sided asymptotically flat spacetime and presents a comprehensive classification of solutions coupled to a conformal scalar field.
