Cosmological model with time varying deceleration parameter in $F(R,G)$ gravity

Santosh V. Lohakare, S. K. Tripathy, B. Mishra

In this paper, we study the dynamical behaviour of the Universe in the $F(R,G)$ theory of gravity, where $R$ and $G$ respectively denote the Ricci scalar and Gauss-Bonnet invariant…
