Abstract

Under the assumption that cold dark matter and dark energy interact with each other through a small coupling term, Q, we constrain the parameter space of the equation of state w of those dark energy fields whose variation of the field since last scattering do not exceed Planck's mass. We use three parameterizations of w and two different expressions for Q. Our work extends previous ones. © 2010 Elsevier B.V. All rights reserved.
