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…
How to delay death and look further into the future if you fall into a black hole
A. V. Toporensky, S. B. Popov
In this note, we present a pedagogical illustration of peculiar properties of motion in the vicinity and inside black holes. We discuss how a momentary impulse can modify the lifet…
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…
