Constraining dynamical dark energy with a divergence-free parametrization in the presence of spatial curvature and massive neutrinos

Hong Li, Xin Zhang

In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z)=w_0+w_a(\frac{\ln (2+z)}{1+z}-\ln 2)$, in the pr…
