Résumé

Physics - General Relativity and Quantum Cosmology

Phys.Rev.D80:061301,2009 We show that within the class of f(R) gravity theories, FLRW power-law perfect fluid solutions only exist for R^n gravity. This significantly restricts the set of exact cosmological solutions which have similar properties to what is found in standard General Relativity.
