Energy-momentum tensorIn de Sitter (dS) gravity, where gravity is a gauge field introduced to realize the local dS invariance of the matter field, two kinds of conservation laws are derived. The first kind is a differential equation for a dS-covariant current, which unites the canonical ...

Several energy-momentum "tensors" of gravitational field are considered andcompared in the lowest approximation. Each of them together withenergy-momentum tensor of point-like particles satisfies the conservation lawswhen equations of motion of particles are the same as in general relativity. Itis ...
