Nonlocal Integral Conservation Laws and Tetradic Currents in the Einstein–Cartan Theory. II. Problem of the Gravitational Energy and Tetradic Currents

摘要

Einstein–Cartan gravitational field equations are formed as Maxwell equations: the codifferential of the tetrad differential is equal to the conserved tetradic current. This yields local integral conservation laws for any tetrad field and, in particular, allows solving the old problem of the gravitational energy in the general relativity and Einstein–Cartan theories.
