We show that it is impossible to determine the state equation of quintessence models on the basis of pure observational SNIa data. An independent estimate of Omega_M0 is necessary. Also in this most favourable case the situation can be problematic.

We show that it is impossible to determine the state equation of quintessence models on the basis of pure observational SNIa data. An independent estimate of Omega_M0 is necessary. Also in this most favourable case the situation can be problematic.File in questo prodotto:
