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…
