We present a systematic approach to embed n-dimensional vacuum general relativity in an (n+1)-dimensional pseudo-Riemannian spacetime whose source is either a (non)zero cosmological constant or a scalar field minimally coupled to Einstein gravity. Our approach allows us to generalize a number of results discussed in the literature. We construct all the possible (physically distinct) embeddings in Einstein spaces, including the Ricci-flat ones widely discussed in the literature. We examine in… 

On the Ck-embedding of Lorentzian manifolds in Ricci-flat spaces

In this paper, we investigate the problem of non-analytic embeddings of Lorentzian manifolds in Ricci-flat semi-Riemannian spaces. In order to do this, we first review some relevant results in the

A study of anisotropic compact stars based on embedding class 1 condition

This paper discusses a generalized model for compact stars, assumed to be anisotropic in nature due to the presence of highly dense and ultra-relativistic matter distribution. After embedding the 4D

On the embedding of Weyl manifolds

We discuss the possibility of extending different versions of the Campbell-Magaard theorem, which have already been established in the context of semi-Riemannian geometry, to the context of Weyl’s

Exploring physical features of anisotropic strange stars beyond standard maximum mass limit in $f\left(R,\mathcal {T}\right)$ gravity

We study a specific model of anisotropic strange stars in the modified |$f\left(R,\mathcal {T}\right)$|-type gravity by deriving solutions to the modified Einstein field equations representing a

A generalized Finch–Skea class one static solution

In the present article, we discuss relativistic anisotropic solutions of Einstein field equations for the spherically symmetric line element under the class I condition. To do so we apply the



Embeddings for 4D Einstein equations with a cosmological constant

There are many ways of embedding a 4D spacetime in a given higher-dimensional manifold while satisfying the field equations. In this work, we extend and generalize a recent paper by Mashhoon and

Geometry and dynamics of the brane-world

Recent developments in string theory have led to 5-dimensional warped spacetime models in which standard-model fields are confined to a 3-brane (the observed universe), while gravity can propagate in

The Embedding of General Relativity in Five-Dimensional Canonical Space: A Short History and a Review of Recent Physical Progress

Einstein theory can be embedded in Kaluza-Klein theory, and in particular all 4D vacuum solutions can be embedded in 5D (pure) canonical space where spacetime is independent of the extra coordinate.

The embedding of space–times in five dimensions with nondegenerate Ricci tensor

We discuss and prove a theorem which asserts that any n-dimensional semi-Riemannian manifold can be locally embedded in an (n+1)-dimensional space with a nondegenerate Ricci tensor which is equal, up

The Schwarzschild–de Sitter solution in five-dimensional general relativity briefly revisited

We briefly revisit the Schwarzschild–de Sitter solution in the context of five-dimensional general relativity. We obtain a class of five-dimensional solutions of Einstein vacuum field equations into

Application of the Campbell-Magaard theorem to higher dimensional physics

Stated succinctly, the original version of the Campbell–Magaard theorem says that it is always possible to locally embed any solution of four-dimensional general relativity in a five-dimensional

Cosmological models in a Kaluza-Klein theory with variable rest mass

A general class of solutions is obtained for a homogeneous, spatially isotropic five-dimensional (5D) Kaluza-Klein theory with variable rest mass. These solutions generalize in the algebraic and

Embeddings in Non-Vacuum Spacetimes

A scheme is discussed for embedding n-dimensional, Riemannian manifolds in an (n + 1)-dimensional Einstein space. Criteria for embedding a given manifold in a spacetime that represents a solution to

Cosmological dynamics on the brane

In Randall-Sundrum-type brane-world cosmologies, the dynamical equations on the three-brane differ from the general relativity equations by terms that carry the effects of embedding and of the free
