Observational Constraints on Nfields Phantom Power-Law
  We investigate the analytical behavior of many scalar fields working collectively, where {\phi} i is the ith scalar field. Furthermore, we evaluate its parameter values by applying certain constraints on our model parameters, and then compare these values with current observational data from Observational data of CMB, BAO and H 0 . Through our results, we deeply observe that in the dark-energy EOS parameter at the Big Rip always finite with the pressure and dark energy density divergence.
