Abstract

In this paper, we investigate coupled quintessence with scaling potential assuming specific forms of the coupling as A namely, αρ̇_̇ṁ, βρ̇_̇ϕ̇ and σ (ρ̇_̇ṁ+ρ̇_̇ϕ̇), 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.
