The Noether formalism for constructing conserved quantities in teleparallel equivalents of general relativity
E. D. Emtsova, A. N. Petrov, A. V. Toporensky
This paper brings a methodological character where we present a comprehensive formalism for constructing conserved quantities in the Teleparallel Equivalent of General Relativity (…
Conserved quantities in STEGR and applications
E. D. Emtsova, A. N. Petrov, A. V. Toporensky
We derive conservation laws in Symmetric Teleparallel Equivalent of General Relativity (STEGR) with direct application of Noether's theorem. This approach allows us to construct co…
General radially moving references frames in the black hole background
A. Toporensky, O. Zaslavskii
We consider general radially moving frames realized in the background of nonextremal black holes having causal structure similar to that of the Schwarzschild metric. In doing so, w…
Ruling out an inflation driven by a power law potential: kinetic coupling does not help
N. Avdeev, A. Toporensky
We demonstrate that the latest constraints on inflationary observables, namely the tensor-to-scalar ratio and the scalar spectral index , from the Cosmic Background Rad…
On Conserved Quantities for the Schwarzschild Black Hole in Teleparallel Gravity
E. D. Emtsova, M. Krššák, A. N. Petrov +1
We examine various methods of constructing conserved quantities in the Teleparallel Equivalent of General Relativity (TEGR). We demonstrate that in the covariant formulation the pr…
On viability of inflation in non-minimal kinetic coupling theory
N. Avdeev, A. Toporensky
We consider initial conditions for inflation in non-minimal kinetic coupling theory. If inflation is driven solely by kinetic term with no potential, the resulting number of e-fold…
Zero-momentum trajectories inside a black hole and high energy particle collisions
A. V. Toporensky, O. B. Zaslavskii
We consider properties of the trajectory with the zero momentum inside a spherically symmetric black hole. We work mostly in the Painlevé% -Gullstrand frame and use the concept of…
Cosmology with nonminimal kinetic coupling and a power-law potential
Maria A. Skugoreva, Sergey V. Sushkov, Alexei V. Toporensky
We consider cosmological dynamics in the theory of gravity with the scalar field possessing a nonminimal kinetic coupling to gravity, , and the power-law potential $…
