Abstract

Averaging problem in GR and cosmology is of fundamental importance. It is still not
clear how to unambiguously average Einstein equations and the metric tensor (despite some promising
attempts). Here we will present a new approach to this problem using the theory of the Cartan
scalars. After short review of the theory originally taken from the equivalence problem, averaging
procedure is presented and some examples are given.
