Stability analysis for cosmological models in f (T, B) gravity

Abstract

In this paper we study cosmological solutions of the f (T, B) gravity using dynamical system analyses. For this purpose, we consider cosmological viable functions of f (T, B) that are capable of reproducing the dynamics of the Universe. We present three specific models of f (T, B) gravity which have a general form of their respective solutions by writing the equations of motion as an autonomous system. Finally, we study its hyperbolic critical points and general trajectories in the phase space of the resulting dynamical variables which turn out to be compatible with the current late-time observations.
