| Abstract: | The cosmological backreaction proposal, which attempts to account for observations without a primary dark energy source in
the stress-energy tensor, has been developed and discussed by means of different approaches. Here, we focus on the concept
of cosmological background solutions in order to develop a framework to study different backreaction proposals. |
