On Some Exponential Potentials for a Cosmological Scalar Field as Quintessence
arXiv:astro-ph/0103335 · doi:10.1023/A:1015395512123
Abstract
We present general exact solutions for two classes of exponential potentials in scalar field models for quintessence. The coupling is minimal and we consider only dust and scalar field. To some extent, it is possible to reproduce experimental results from supernovae.
