Nonflat time-variable dark energy cosmology
  We generalize the time-variable dark energy scalar field $\Phi$ model
($\Phi$CDM) to nonflat 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 nonflat
geometry.
