Dynamics of interacting quintessence

In this paper, we investigate coupled quintessence with scaling potential assuming specific forms of the coupling as $A$ namely, $\alpha \dot{{\rho }_m}$, $\beta \dot{{\rho }_{\varphi }}$ and $\sigma (\dot{{\rho }_m}+\dot{{\rho }_{\varphi }})$, 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 ${\mathrm{\Omega }}_{DE}\mathrm{/}{\mathrm{\Omega }}_{DM}$ of order unity in order to alleviate the coincidence problem.
