2 00 3 Classification of Energy Momentum Tensors in n ≥ 5 Dimensional Space - times : a Review
Recent developments in string theory suggest that there might exist extra spatial dimensions, which are not small nor compact. The framework of a great number of brane cosmological models is that in which the matter fields are confined on a brane-world embedded in five dimensions (the bulk). Motivated by this we review the main results on the algebraic classification of second order symmetric t...
متن کاملOn the Algebraic Structure of Second Order Symmetric Tensors in 5-Dimensional Space-times
A new approach to the algebraic classification of second order symmetric tensors in 5-dimensional space-times is presented. The possible Segre types for a symmetric two-tensor are found. A set of canonical forms for each Segre type is obtained. A theorem which collects together some basic results on the algebraic structure of the Ricci tensor in 5-dimensional space-times is also stated. ∗ inter...
متن کاملEnergy-Momentum Tensors in Nonsimple Elastic Dielectrics
We use Noether's theorem to derive energy-momentum tensors for a simple elastic material, a nonsimple elastic material of grade two, a simple elastic dielectric and a nonsimple elastic dielectric of grade two. The technique is easily extendable to a nonsimple elastic dielectric of any grade. Introduction The concept of the force acting on a defect, e.g., an impurity, vacant lattice site, disloc...
متن کاملElectromagnetic energy-momentum tensors in media
It is pointed out that the previous energy-momentum tensors of Minkowski and Abraham for the electromagnetic field in continuous media are based on a covariant formulation which does not reflect a symmetry inherent to the system. Instead, taking into account the intrinsic invariance under Lorentz transformations involving the reduced speed of light in such a medium, a compact and fully consiste...
متن کاملEnergy-Momentum Tensors for Dispersive Electromagnetic Waves
Classical relativistic field theory is used as a basis for a general discussion of the problem of splitting up the total energy-momentum tensor ofa system into contributions from its component subsystems. Both the Minkowski and Abraham forms (including electrostriction) arise naturally in alternative split-up procedures applied to a nondispersive dielectric fluid. The case of an electromagnetic...
