Energy conditions in f(T) gravity with higher-derivative torsion terms
, 2017 We study the energy conditions in the framework of the modified 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 ...
