Abstract
Recently, a new model obtained from generalizing teleparallel gravity, named f(T) theory, is proposed to explain the present cosmic accelerating expansion with no need of dark energy. In this Letter, we analyze the dynamical property of this theory. For a concrete power law model, we obtain that the dynamical system has a stable de Sitter phase along with an unstable radiation dominated phase and an unstable matter dominated one. We show that the Universe can evolve from a radiation dominated era to a matter dominated one, and finally enter an exponential expansion phase.
