Bibliographic description in the original language

P. Petriakova Sub-Planckian Scale and Limits for f(R) Models / Petriakova, P.; Popov, A.; Rubin, S. // Symmetry. - 2021. - V.13. - P.313. https://doi.org/10.3390/sym13020313

Annotation

We study the universe evolution starting from the sub-Planckian scale to present times. The requirement for an exponential expansion of the space with the observed metric as a final stage leads to significant restrictions on the parameter values of a function f(R). An initial metric of the universe should be maximally symmetric with the positive curvature.

Keywords

f(R) gravity, cosmology, Planck energies

The name of the journal
