摘要
In this paper, we examine the interacting dark energy model in f(T) cosmology. We assume dark energy as a perfect fluid and choose a specific cosmologically viable form f(T) = beta aeT. We show that there is one attractor solution to the dynamical equation of f(T) Friedmann equations. Further we investigate the stability in phase space for a general f(T) model with two interacting fluids. By studying the local stability near the critical points, we show that the critical points lie on the sheet u* = (c - 1)v* in the phase space, spanned by coordinates (u, v, Omega, T). From this critical sheet, we conclude that the coupling between the dark energy and matter c a (-2, 0).
