Comment on "Einstein's Other Gravity and the Acceleration of the Universe''

Kazuharu Bamba, Chao-Qiang Geng, Chung-Chi Lee

We show that in the exponential $f (T)$ model studied by E. Linder [arXiv:1005.3039, Phys.Rev.D 81, 127301 (2010)], it is impossible to have the crossing of the phantom divide line…

Cosmological evolution in exponential gravity

Kazuharu Bamba, Chao-Qiang Geng, Chung-Chi Lee

We explore the cosmological evolution in the exponential gravity $f (R) = R + c_{1} (1 - e^{- c_{2} R})$ ( $c_{1, 2} = constant$ ). We summarize various viability conditions and expli…
