Energy conditions in f(T) gravity with higher-derivative torsion terms
arXiv:1701.00796 · doi:10.1209/0295-5075/117/60003
Abstract
We study the energy conditions in the framework of the modi- fied gravity with higher-derivative torsional terms in the action. We discuss the viability of the model by studying the energy conditions in terms of the cosmographical parameters like Hubble, deceleration, jerk, snap and lerk parameters. In particular, We consider two spe- cific models that are proposed in literature and examine the viability bounds imposed by the weak energy condition.
