A reconstruction scheme for f(T)f(T) gravity and its consequences in the perturbation level
Abstract
The present study reports a reconstruction scheme for f(T)f(T) gravity considering the scale factor in the power law form. The equation of state parameter has been studied for this reconstructed model along with the deceleration parameter and the statefinder pair {r,s}{r,s}. The statefinder trajectory has been found to interpolate between dust and ΛΛCDM phase of the universe. Cosmological evolution of primordial perturbations has been studied through scalar metric fluctuations and finally the reconstructed f(T)f(T) model has been tested for its consistency with the generic expansion of the universe.
