FRW in quadratic form of f(T) gravitational theories
© 2015, Springer Science+Business Media New York. We derive asymptote solution of a homogeneous and isotropic universe governed by the quadratic form of the field equation of f(T) gravity. We explain how the higher order of the torsion can provide an origin for late accelerated phase of the universe in the FRW. The solution makes the scalar torsion T to be a function of the cosmic time t. We show that for the equation of state $$p=\omega \rho $$p=ωρ with $$\omega \ne -1$$ω≠-1 the scale factor represent late phase of universe. We perform the cosmological studies and show how the quadratic form of f(T) effect on the behavior of these studies.
