Singularity Problem in Teleparallel Dark Energy Models
Chao-Qiang Geng, Je-An Gu, Chung-Chi Lee
We study future singularity in teleparallel dark energy models, particularly its behavior and its (non)occurrence in the observationally viable models. For the models with a genera…
Einstein Static Universe in Exponential Gravity
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 gravity theories. We show that the stable solutions exist in these two m…
Asymptotic Cosmological Behavior of Scalar-Torsion Mode in Poincare Gauge Theory
Chao-Qiang Geng, Chung-Chi Lee, Huan-Hsin Tseng
We study the cosmological effect of the simple scalar-torsion () mode in Poincaré gauge theory of gravity. We find that for the non-constant (affine) curvature case, the early…
