Constraints on the exponential $f (R)$ model from latest Hubble parameter measurements

Yun Chen, Chao-Qiang Geng, Chung-Chi Lee +2

We investigate the viable exponential $f (R)$ gravity in the metric formalism with $f (R) = - β R_{s} (1 - e^{- R / R_{s}})$ . The latest sample of the Hubble parameter measurements with 23 data p…

$Λ (t)$ CDM Model as a Unified Origin of Holographic and Agegraphic Dark Energy Models

Yun Chen, Zong-Hong Zhu, Lixin Xu +1

Motivated by the fact that any nonzero $Λ$ can introduce a length scale or a time scale into Einstein's theory, $r_{Λ} = c t_{Λ} = 3/∣Λ∣$ . Conversely, any cosmological length scale o…
