Constraining f(T) gravity by dynamical system analysis
Abstract
We investigate the cosmological solutions of the f(T) gravity theory using the method of dynamical systems. For this purpose a general form of the f(T) function is considered and four conditions are defined that they have to satisfy in order to describe the standard cosmological history. We examine the power law, and another form of f(T) against these conditions. For a power law function f(T)= B(-T)β, β must be less than one and unequal to 12 to obtain a consistent cosmological model. We also investigate a model of inflation in this theory.
