QUINTESSENCE AND THE FIRST DOPPLER PEAK

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, Ω_k, for any value of the ratio Ω_Λ/Ω_M, so that such a dependence is perfectly valid in the range suggested by supernova observations.
