Next-generation galaxy redshift surveys will open up an exciting opportunity for precision determinations of neutrino masses. Here, we discuss the prospects for measuring the neutrino masses, including properly the non-linear gravitational evolution of matter power spectrum for a mixed dark matter model (neutrinos plus cold dark matter). Based on the perturbation theory, the effect of non-linearity is quantified. Moreover, using Fisher matrix analysis, we present how the neutrino masses will be determined for future galaxy redshift survey.
