On the Energy-Momentum and Spin Tensors in the Riemann-Cartan Space
Robert R. Lompay
General classical theories of material fields in an arbitrary Riemann-Cartan space are considered. For these theories, with the help of equations of balance, new non-trivially gene…
Covariant Differential Identities and Conservation Laws in Metric-Torsion Theories of Gravitation. II. Manifestly Generally Covariant Theories
Robert R. Lompay, Alexander N. Petrov
The present paper continues the work of the authors [arXiv:1306.6887 [gr-qc]]. Here, we study generally covariant metric-torsion theories of gravity presented more concretely, sett…
Covariant Differential Identities and Conservation Laws in Metric-Torsion Theories of Gravitation. I. General Consideration
Robert R. Lompay, Alexander N. Petrov
Arbitrary diffeomorphically invariant metric-torsion theories of gravity are considered. It is assumed that Lagrangians of such theories contain derivatives of field variables (ten…
Covariantized Noether identities and conservation laws for perturbations in metric theories of gravity
Alexander N. Petrov, Robert R. Lompay
A construction of conservation laws and conserved quantities for perturbations in arbitrary metric theories of gravity is developed. In an arbitrary field theory, with the use of i…
Deriving Mathisson - Papapetrou equations from relativistic pseudomechanics
R. R. Lompay
It is shown that the equations of motion of a test point particle with spin in a given gravitational field, so called Mathisson - Papapetrou equations, can be derived from Euler -…
