General solution of scalar field cosmology with a (piecewise) exponential potential
arXiv:1105.4515 · doi:10.1088/1475-7516/2011/10/004
Abstract
We study in detail the general solution for a scalar field cosmology with an exponential potential, correcting some imprecisions, encountered previously in the literature. In addition, we generalize this solution for a piecewise exponential potential, which is continuous, but not smooth (with cusps).
