Viable f(R) Scenarios Unifying Inflation with Realistic Dynamical Dark Energy
S. D. Odintsov, V. K. Oikonomou, G. S. Sharov
Two gravity models are tested on the basis of their viability during all stages of cosmological evolution. It is shown that these models can describe both the early-time inf…

Dynamical Dark Energy from Gravity Models Unifying Inflation with Dark Energy: Confronting the Latest Observational Data
S. D. Odintsov, V. K. Oikonomou, G. S. Sharov
A class of viable gravity models which can provide a unified description of inflation with the dark energy era is confronted with the latest observational data on the dark e…

Einstein-Gauss-Bonnet Cosmology Confronted with Observations
S. D. Odintsov, V. K. Oikonomou, German S. Sharov
Several models within the framework of Einstein-Gauss-Bonnet gravities are considered with regard their late-time phenomenological viability. The models contain a non-minimally cou…
