    Abstract:

    Cold dark matter and dark energy may interact weakly with one another via some coupling term, Q. Taking this into account, we constrain the parameter space of the equation of state w of dark energy fields assuming that the variation of the field since last scattering does not exceed Planck’s mass. We consider three w parametrizations and two expressions for Q. This work extends previous ones.
