Einstein Static Universe in Exponential $f(T)$ Gravity    [PDF]

Jung-Tsung Li, Chung-Chi Lee, Chao-Qiang Geng

We analyze the stability of the Einstein static closed and open universe in two types of exponential $f(T)$ gravity theories. We show that the stable solutions exist in these two models. In particular, we find that large regions of parameter space in equation of state $w=p/\rho$ for the stable universe are allowed in the $f(T)$ theories.
