The way to the Big Bang
Victor Berezin, Inna Ivanova, Anastasia Kuprina
We propose conformal invariance as a fundamental symmetry governing cosmological particle creation from vacuum fluctuations, employing a phenomenological approach with an ideal flu…

Induced gravity and cosmological principle
V. A. Berezin, I. D. Ivanova, A. E. Kuprina
The phenomenological description of the cosmological particle production in the framework of the induced gravity is investigated. It appears that the source terms with the particle…

Conformally Invariant Gravity and Gravitating Mirages
Victor Berezin, Inna Ivanova
The action of an ideal fluid in Euler variables with a variable number of particles is used for the phenomenological description of the processes of particle creation in strong ext…
