Observational evidence indicating that the expansion of the universe is
accelerating has surprised cosmologists in recent years. Cosmological models
have sought to explain this acceleration by incorporating `dark energy', of
which the traditional cosmological constant is just one possible candidate.
Several cosmological models involving an evolving equation of state of the dark
energy have been proposed, as well as possible energy exchange to other
components, such as dark matter. This paper summarises the forms of the most
prominent models and discusses their implications for cosmology and
astrophysics. Finally, this paper examines the current and future observational
constraints on the nature of dark energy.
