Аннотация
© 2021 by the authors. Licensee MDPI, Basel, Switzerland.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.
