Ghost-free $F (R, G)$ Gravity

S. Nojiri, S. D. Odintsov, V. K. Oikonomou +1

In this work we shall address the ghost issue of $F (R, G)$ gravity, which is known to be plagued with ghost degrees of freedom. These ghosts occur due to the…

Sub-Planckian scale and limits for $f (R)$ models

P. M. Petryakova, Arkady A. Popov, Sergey G. Rubin

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 fina…
