In the Friedmann-Lema\\^itre-Robertson-Walker universe, the existence of a nontrivial conservation law indicates the integrability of the field equations. Due to the complexity of the latter, we apply the differential invariants approach in order to construct special power-law solutions and study their stability.","authors_text":"Alex Giacomini, Andronikos Paliathanasis, Genly Leon, N.
