Query: Dark energy effects in the Cosmic Microwave Background Radiation   Understanding the nature of the dark energy is one of the most important task
in cosmology. In principle several cosmological observations can be used to
discriminate amid a static cosmological constant contribution and a dynamical
quintessence component. In view of the upcoming high resolution CMB
experiments, using a model independent approach we study the dark energy
imprint in the CMB anisotropy power spectrum and the degeneracy with other
cosmological parameters.
