Four-index energy-momentum tensors for gravitation and matter [1]
Abstract
The 4-index energy-momentum tensors for gravitation and matter are analyzed on the basis of new equations for the gravitational field with the Riemann tensor. Some properties of such defined gravitational energy are discussed.
