Quintessence and the first Doppler peak

Abstract

By using a tracking quintessence model we obtain that the position of the first Doppler peak in the spectrum of CMB anisotropies only depends on the topology of the universe, ${\Omega }_k$, for any value of the ratio ${\Omega }_{\Lambda }/{\Omega }_M$, so that such a dependence is perfectly valid in the range suggested by supernova observations.
