Constraining dynamical dark energy with a divergence-free parametrization in the presence of spatial curvature and massive neutrinos
Constraining dynamical dark energy divergence-free parametrization presence spatial curvature massive neutrinos
2012/2/21
In this paper, we report the results of constraining the dynamical dark energy with a divergence-free parameterization, $w(z) = w_{0} + w_{a}(\frac{\ln(2+z)}{1+z}-\ln2)$, in the presence of spatial cu...

We investigate f(T) cosmology in both the background, as well as in the perturbation level, and we present the general formalism for reconstructing the equivalent one-parameter family of f(T) models f...
