Palatini formulation of the modified gravity with an additionally squared scalar curvature term
Xin He Meng, Peng Wang
In this paper by deriving the Modified Friedmann equation in the Palatini formulation of gravity, first we discuss the problem of whether in Palatini formulation an additiona…

corrections to the cosmological dynamics of inflation in the Palatini formulation
Xin-He Meng, Peng Wang
We investigate the corrections to the inflationary cosmological dynamics due to a term in the Palatini formulation which may arise as quantum corrections to the effective Lag…

Gravitational potential in Palatini formulation of modified gravity
Xin-He Meng, Peng Wang
General Relativity has so far passed almost all the ground-based and solar-system experiments. Any reasonable extended gravity models should consistently reduce to it at least in t…
