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