We examine generalizations of the five-dimensional canonical metric by including a dependence of the extra coordinate in the four-dimensional metric. We discuss a more appropriate way to interpret the four-dimensional energy-momentum tensor induced from the five-dimensional space-time and show it can lead to quite different physical situations depending on the interpretation chosen. Furthermore, we show that the assumption of five-dimensional null trajectories in Kaluza-Klein gravity can… 

On higher-dimensional dynamics

Technical results are presented on motion in N(>4)D manifolds to clarify the physics of brane theory, Kaluza–Klein theory, induced-matter theory, and string theory. The so-called canonical or warp

Mass and Charge in Brane-World and Non-Compact Kaluza-Klein Theories in 5 Dim

In classical Kaluza-Klein theory, with compactified extra dimensions and without scalar field, the rest mass as well as the electric charge of test particles are constants of motion. We show that in

The Principle of least action for test particles in a four-dimensional spacetime embedded in 5D

It is well known that, in the five-dimensional scenario of braneworld and space–time-mass theories, geodesic motion in 5D is observed to be non-geodesic in 4D. Usually, the discussion is purely

Invariant Definition of Rest Mass and Dynamics of Particles in 4D from Bulk Geodesics in Brane-World and Non-Compact Kaluza Klein Theories

In the Randall–Sundrum brane-world scenario and other non-compact Kaluza–Klein theories, the motion of test particles is higher-dimensional in nature. In other words, all test particles travel on

Physics in higher-dimensional manifolds

In this thesis, we study various aspects of physics in higher-dimensional manifolds involving a single extra dimension. After giving some historical perspective on the motivation for studying

FLRW UNIVERSES FROM "WAVE-LIKE" COSMOLOGIES IN 5D

We consider the evolution of a 4D-universe embedded in a five-dimensional (bulk) world with a large extra dimension and a cosmological constant. The cosmology in 5D possesses "wave-like" character in

Extra force from an extra dimension. Comparison between brane theory, STM and other approaches

We investigate the question of how an observer in 4D perceives the five-dimensional geodesic motion. We consider the interpretation of null and non-null bulk geodesics in the context of brane theory,

VARIATION OF G, Λ(4) AND VACUUM ENERGY FROM BRANE-WORLD MODELS

In brane-world theory in five dimensions, the bulk metric is usually written in Gaussian coordinates, where g4μ = 0 and g44 = -1. However, the choice g44 = -1 is an external condition, not a

An Analytic model for the transition from decelerated to accelerated cosmic expansion

We consider the scenario where our observable universe is devised as a dynamical four-dimensional hypersurface embedded in a five-dimensional bulk space–time, with a large extra dimension, which is

Dynamics in Kaluza-Klein Gravity and a Fifth Force

Using a novel coordinate system, we rederive the field equations and equa tions of motion for 5-dimensional relativity in the general case where the metric can depend on all 5 coordinates (i.e.,

A Hamiltonian Treatment of Five-Dimensional Kaluza-Klein Gravity

We give a Hamiltonian treatment of 5D vacuum Kaluza–Klein theory that is unrestricted in the extra coordinate dependence. When the extra coordinate dependence is removed from the 5D metric we recover

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

A Physical Interpretation of Kaluza-Klein Cosmology

A new interpretation of five-dimensional Kaluza-Klein gravity is suggested, wherein the density and pressure of the usual four-dimensional energy-momentum tensor (T ij ) are regarded as the extra

Gauge conditions in modern Kaluza–Klein theory

In the modern version of 5-D general relativity where the fifth dimension induces matter in 4-D space–time, a choice of coordinates and its restrictions on the geometry (a gauge) dictates the physics

The embedding of General Relativity in five dimensions

We argue that General Relativistic solutions can always be locally embedded in Ricci-flat 5-dimensional spaces. This is a direct consequence of a theorem of Campbell (given here for both a timelike

Class of exact solutions in 5D gravity and its physical properties.

TLDR
A class of solutions of the field equations of five-dimensional general relativity that is static and spherically symmetric in ordinary three-dimensional space is derived, which could be used with data on gravitational lensing to look for a fifth dimension.

A THEORY OF SPACE, TIME AND MATTER

We unify the gravitational field with its source by considering a new type of 5D manifold in which space and time are augmented by an extra dimension which induces 4D matter. The classical tests of

D-dimensional gravity from (D + 1) dimensions

We generalize Wesson's procedure, whereby vacuum (4 + 1)-dimensional field equations give rise to (3 + 1)-dimensional equations with sources, to arbitrary dimensions. We then employ this
