# Constraints on the redshift dependence of the dark energy potential

@article{Simn2005ConstraintsOT, title={Constraints on the redshift dependence of the dark energy potential}, author={Joan Sim{\'o}n and Licia Verde and Raul Jimenez}, journal={Physical Review D}, year={2005}, volume={71}, pages={123001} }

We develop a formalism to characterize the shape and the redshift evolution of the dark energy potential. Our formalism makes use of quantities similar to the horizon-flow parameters in inflation and is general enough that can deal with multiscalar quintessence scenarios, exotic matter components, and higher-order curvature corrections to General Relativity. We show how the shape of the dark energy potential can be recovered nonparametrically using this formalism and we present approximations… Expand
