Cosmic Acceleration and M Theory Cosmology
Abstract
This is a short overview of spatially flat (or open) fourdimensional accelerating cosmologies for some simple exponential potentials obtained by string or M theory compactification on some nontrivial curved spaces, which may lead to some striking results, e.g., the observed cosmic acceleration and the scale of the dark energy from first principles.
