Galileon versus Quintessence: A comparative phase space analysis and late-time cosmic relevance
Light-mass Galileon models with cubic interactions and three tested potentials have no stable late-time accelerating attractors in phase space, unlike quintessence which has stable de-Sitter attractors for cosh potentials.
