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.
