Applied Cosmography: A Pedagogical Review
by Yu. L. Bolotin, et al. - arXiv.org , 2018
Cosmography is in fact a kinematics of cosmological expansion. The effectiveness of cosmography lies in the fact that it allows, based on the observations, to perform a rigid selection of models that do not contradict the cosmological principle.

Cosmology
by V. A. Rubakov - arXiv.org , 2018
