Unveiling cosmography from the dark energy equation of state
  Constraining the dark energy equation of state, $w_x(z)$, is one of the main
issues of current and future cosmological surveys. In practice, this requires
making assumptions about the evolution of $w_x$ with redshift $z$, which can be
manifested in a choice of a specific parametric form where the number of
cosmological parameters play an important role in the observed cosmic
acceleration. Since any attempt to constrain the EoS requires fixing some prior
in one form or the other, settling a method to constrain cosmological
parameters is of great importance. In this paper, we provide a straightforward
approach to show how cosmological tests can be improved via a parametric
methodology based on cosmography. Using Supernovae Type IA samplers we show how
by performing a statistical analysis of a specific dark energy parameterisation
can give directly the cosmographic parameters values.
