Singularity softening and avoidance by the action of thermal radiation in a generalized entropic cosmology
E. Elizalde, A. V. Yurov, A. V. Timoshkin
Some relevant aspects of a new form of generalized entropic cosmology, recently introduced by Nojiri, Odintsov and Faraoni, are considered. The setup is a logarithmic equation of s…
Quantum Cosmology Without Singularities: A New Approach
Valerian A. Yurov, Artyom V. Yurov
The article is dedicated to a discussion regarding the role of Barrow's ''Zero Universes'' in quantum cosmology. In particular, we demonstrate that if quantum gravity effects are m…
Holographic bounce cosmological models induced by viscous dark fluid from a generalized non-singular entropy function
E. Elizalde, A. V. Yurov, A. V. Timoshkin
Bounce cosmological models containing a dark viscous fluid in a spatially flat Friedmann-Robertson-Walker (FRW) universe are considered. The universe evolution is described in term…
Little Rip, Pseudo Rip and bounce cosmology from generalized equation of state in the Universe with spatial curvature
A. V. Timoshkin, A. V. Yurov
We consider the Little Rip (LR), Pseudo Rip (PR) and bounce cosmological models in the Friedmann-Robertson-Walker (FRW) metric with nonzero spatial curvature. We describe the evolu…
The Cosmological Arrow of Time and the Retarded Potentials
Alla Yurova, Artyom Yurov, Valerian Yurov
We demonstrate that the cosmological arrow of time is the cause for the arrow of time associated with the retarded radiation. This implies that the proposed mathematical model serv…
On the Question of the Bäcklund Transformations and Jordan Generalizations of the Second Painlevé Equation
Artyom Yurov, Valerian Yurov
We demonstrate the way to derive the second Painlevé equation and its Bäcklund transformations from the deformations of the Nonlinear Schrödinger equation (NLS), all the whil…
