Abstract
We discuss a degeneracy between the geometry of the universe and the dark energy equation of state wX which exists in the power spectrum of the cosmic microwave background. In particular, for the case with wX<−1, this degeneracy has interesting implications to a lower bound on wX from observations. It is also discussed how this degeneracy can be removed using current observations of type Ia supernovae.
