1307.7399 (Anatoly Pavlov et al.)

Non-flat time-variable dark energy cosmology    [PDF]

Anatoly Pavlov, Shawn Westmoreland, Khaled Saaidi, Bharat Ratra
We generalize the time-variable dark energy scalar field $\Phi$ model ($\Phi$CDM) to non-flat space. We show that even in the space-curvature-dominated epoch the scalar field solution is a time-dependent fixed point or attractor, with scalar field energy density that grows relative to the energy density in spatial curvature. This is the first example of a physically consistent and complete model of dynamical dark energy in a non-flat geometry.
