| 英文摘要 | ABSTRACT We investigate two dark energy cosmological models (i.e., the ΛCDM and ?CDM models) with massive neutrinos assuming two different neutrino mass hierarchies in both the spatially flat and non-flat scenarios, where in the ?CDM model the scalar field possesses an inverse power-law potential, V(?)?∝???α (α?>?0). Cosmic microwave background data from Planck?2015, baryon acoustic oscillation data from 6dFGS, SDSS-MGS, BOSS-LOWZ and BOSS CMASS-DR11, the joint light-curve analysis compilation of SNe Ia apparent magnitude observations, and the Hubble Space Telescope H0 prior, are jointly employed to constrain the model parameters. We first determine constraints assuming three species of degenerate massive neutrinos. In the spatially flat (non-flat) ΛCDM model, the sum of neutrino masses is bounded as Σmν? |
