Conserved Currents and Superpotentials in Teleparallel Equivalent of General Relativity
Elena Emtsova, Alexander Petrov, Aleksey Toporensky
We study the Teleparallel Equivalent of General Relativity (TEGR) with Lagrangian that includes the flat (inertial) spin connection and that is evidently invariant with respect to…

Post-Newtonian limit of scalar-torsion theories of gravity as analogue to scalar-curvature theories
Elena D. Emtsova, Manuel Hohmann
We consider a recently proposed class of extended teleparallel theories of gravity, which entail a scalar field which is non-minimally coupled to the torsion of a flat, metric-comp…

Velocities of distant objects in General Relativity revisited
Elena Emtsova, Alexey Toporensky
We consider two most popular definitions of velocities of remote objects in General Relativity. Our work has two motivations. From a research point of view, we generalize the formu…
