reconstruction of f(T) gravity

What is it about?

The present work reports a reconstruction scheme for f(T) gravity based on QCD ghost dark energy. Two models of f(T) have been generated and the pressure and density contributions due to torsion have been reconstructed. Two realistic models have been obtained and the effective equations of state have been studied. Also, the squared speed of sound has been studied to examine the stability of the models.

Why is it important?

In the present work we have studied a reconstruction scheme for $f(T)$ gravity based on QCD ghost dark energy. In the modified field equations we have considered $\rho$ as the $\rho_{gde}$ in a flat universe with power law form of the scale factor. Because of the choice of the scale factor, the $\rho_{gde}$ could be expressed as a function of $t$. Subsequently, considering the two field equations, we have reconstructed $f(T)$ in two forms described as Case I and Case II respectively and given in
