Limits of the energy-momentum tensor in general relativity
نویسندگان
چکیده
A limiting diagram for the Segre classification of the energy-momentum tensor is obtained and discussed in connection with a Penrose specialization diagram for the Segre types. A generalization of the coordinate-free approach to limits of Paiva et al. to include non-vacuum space-times is made. Geroch’s work on limits of space-times is also extended. The same argument also justifies part of the procedure for classification of a given spacetime using Cartan scalars. pacs numbers: 04.20.-q 04.20.Cv 04.20.Jb

Bulk Viscous Bianchi Type VI0 Cosmological Model in the Self-creation Theory of Gravitation and in the General Theory of Relativity
In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...
متن کاملLimits of space-times in five dimensions and their relation to the Segre Types
A limiting diagram for the Segre classification in 5-dimensional space-times is obtained, extending a recent work on limits of the energy-momentum tensor in general relativity. Some of Geroch’s results on limits of space-times in general relativity are also extended to the context of five-dimensional Kaluza-Klein space-times. pacs numbers: 04.20.Cv 04.50.+h 04.20.Jb 04.20.-q
متن کاملQuasi-local definitions of energy in general relativity
Defining energy is a surprisingly difficult problem in general relativity. For instance, the energy density of the gravitational field of a planet at a particular point could be determined by a comoving observer measuring the kinetic energy of a freely falling object. Due to the equivalence principle both the object and the observer fall at equal rates. Therefore, the observer would not assign ...
متن کاملEinstein structures on four-dimensional nutral Lie groups
When Einstein was thinking about the theory of general relativity based on the elimination of especial relativity constraints (especially the geometric relationship of space and time), he understood the first limitation of especial relativity is ignoring changes over time. Because in especial relativity, only the curvature of the space was considered. Therefore, tensor calculations should be to...
متن کاملDescription of charged scalar system by means of General Relativity approach
The Kähler metric which has been constructed by present author in [1] is used in this paper to find an exact solution of Einstein equations with energy-momentum tensor of special type. That type of Tij admits in particular to use it as energy-momentum tensor of charged scalar field and in case of such system the field function is determined.
