Conserved currents in gravitational models with quasi-invariant Lagrangians: Application to teleparallel gravity
Yuri N. Obukhov, Guillermo F. Rubilar, J. G. Pereira
Conservation laws in gravitational theories with diffeomorphism and local Lorentz symmetry are studied. Main attention is paid to the construction of conserved currents and charges…
Recent developments in premetric classical electrodynamics
Friedrich W. Hehl, Yakov Itin, Yuri N. Obukhov
Classical electrodynamics can be based on the conservation laws of electric charge and magnetic flux. Both laws are independent of the metric and the linear connection of spacetime…
Invariant conserved currents in gravity theories with local Lorentz and diffeomorphism symmetry
Yuri N. Obukhov, Guillermo F. Rubilar
We discuss conservation laws for gravity theories invariant under general coordinate and local Lorentz transformations. We demonstrate the possibility to formulate these conservati…
Covariance properties and regularization of conserved currents in tetrad gravity
Yuri N. Obukhov, Guillermo F. Rubilar
We discuss the properties of the gravitational energy-momentum 3-form within the tetrad formulation of general relativity theory. We derive the covariance properties of the quantit…
Poincare gauge gravity: selected topics
Yuri N. Obukhov
In the gauge theory of gravity based on the Poincare group (the semidirect product of the Lorentz group and the spacetime translations) the mass (energy-momentum) and the spin are…
Plane waves in metric-affine gravity
Yuri N. Obukhov
We describe plane-fronted waves in the Yang-Mills type quadratic metric-affine theory of gravity. The torsion and the nonmetricity are both nontrivial, and they do not belong to th…
