Description

We present a dark energy model with a double exponential potential for a minimally coupled scalar field, which allows general exact integration of the cosmological equations. The solution can perfectly emulate a Λ-term model at low-medium redshift, exhibits tracking behavior, and does not show eternal acceleration
