Late time acceleration in Palatini gravity
We investigate the effect of the quadratic correction αR$^{2}$ and non-minimal coupling ξϕ$^{2}$R on a quintessence model with an exponential potential V(ϕ) = M$^{4}$exp(−λϕ) in the Palatini formulation of gravity. We use dynamical system techniques to analyze the attractor structure of the model an...
