BAO cosmography
  Cosmography provides a model-independent way to map the expansion history of
the Universe. In this paper we simulate a Euclid-like survey and explore
cosmographic constraints from future Baryonic Acoustic Oscillations (BAO)
observations. We derive general expressions for the BAO transverse and radial
modes and discuss the optimal order of the cosmographic expansion that provide
reliable cosmological constraints. Through constraints on the deceleration and
jerk parameters, we show that future BAO data have the potential to provide a
model-independent check of the cosmic acceleration as well as a discrimination
between the standard $\Lambda$CDM model and alternative mechanisms of cosmic
acceleration.
