Abstract

We investigate the correlation between the neutrino mass limit and dark energy with time evolving equation of state. Parameterizing dark energy as w=w0+w1*z/(1+z), we make a global fit using Markov Chain Monte Carlo technique to determine w0, w1, neutrino mass as well as other cosmological parameters simultaneously. We pay particular attention to the correlation between neutrino mass Σmν and w1 using current cosmological observations as well as the future simulated datasets such as PLANCK, SNAP and LAMOST.
