Cosmological model with time varying deceleration parameter in F(R,G) gravity
Abstract
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. Our wide analysis encompasses the energy conditions, cosmographic parameters, Om(z) diagnostic, stability and the viability of reconstructing the referred model through a scalar field formalism. The model obtained here shows the quintessence like behaviour at late times.
