Quasi-Local Energy-Momentum and Angular Momentum in General Relativity
The present status of the quasi-local mass, energy-momentum and angular-momentum constructions in general relativity is reviewed. First, the general ideas, concepts, and strategies, as well as the necessary tools to construct and analyze the quasi-local quantities, are recalled. Then, the various specific constructions and their properties (both successes and deficiencies are discussed. Finally...
متن کاملDe Sitter Special Relativity
A special relativity based on the de Sitter group is introduced. Like ordinary special relativity, it retains the quotient character of spacetime, and consequently a notion of homogeneity. This means that the underlying spacetime will be a de Sitter spacetime, the quotient space between de Sitter and the Lorentz groups. Since the local symmetry will also be given by the de Sitter group, each ta...
متن کاملEnergy-Momentum and Angular Momentum Carried by Gravitational Waves in Extended New General Relativity
In an extended, new form of general relativity, which is a teleparallel theory of gravity, we examine the energy-momentum and angular momentum carried by gravitational wave radiated from Newtonian point masses in a weak-field approximation. The resulting wave form is identical to the corresponding wave form in general relativity, which is consistent with previous results in teleparallel theory....
متن کاملIntrinsic angular momentum in general relativity
There are several definitions of the notion of angular momentum in general relativity. However none of them can be said to capture the physical notion of intrinsic angular momentum of the sources in the presence of gravitational radiation. We present a definition which is appropriate for the description of intrinsic angular momentum in radiative spacetimes. This notion is required in calculatio...
متن کاملThe Elastic Energy-Momentum Tensor in Special Relativity
We consider the standard nonrelativistic theory of a continuous, elastic medium with finite deformations, according to which the elastic energy is a function only of the state of strain, and the elastic stress tensor is proportional to the strain gradient of the elastic energy in appropriate coordinates. We derive a special relativistic, energy-momentum tensor, which yields the standard class o...
