Inflection Point Quintessence

We examine models in which the accelerated expansion of the universe is driven by a scalar field rolling near an inflection point in the potential. For the simplest such models, in which the potential is of the form V(\phi) = V_0 + V_3 (\phi-\phi_0)^3, the scalar field can either evolve toward \phi...
