Dynamics of interacting quintessence

In this paper, we investigate coupled quintessence with scaling potential assuming specific forms of the coupling as A namely, α ρ ̇ₘ , β ρ ̇φ and σ (ρ ̇ₘ+ρ ̇φ) , and present phase space analysis for three different interacting models. We focus on the attractor solutions that can give rise to late time acceleration with Ω _DE/Ω _DM of order unity in order to alleviate the coincidence problem.
