Abstract

In this paper, we explore the cosmological implications of interacting dark energy model in a torsion-based gravity namely f(T). Assuming that dark energy interacts with dark matter and radiation components, we examine the stability of this model by choosing different forms of interaction terms. We consider three different forms of dark energy: cosmological constant, quintessence and phantom energy. We then obtain several attractor solutions for each dark energy model interacting with the other components. This model successfully explains the coincidence problem via the interacting dark energy scenario.
