Transient Quintessence from Group Manifold Reductions or . . .
We investigate the accelerating phases of cosmologies supported by a metric, scalars and a single exponential scalar potential. The different solutions can be represented by trajectories on a sphere and we find that quintessence happens within the “arctic circle” of the sphere. Furthermore, we obtai...
