title = "Cosmology with Ricci-type dark energy",
abstract = " We consider the dynamics of a cosmological substratum of pressureless matter and holographic dark energy with a cutoff length proportional to the Ricci scale. Stability requirements for the matter perturbations are shown to single out a model with a fixed relation between the present matter fraction Ω m0 and the present value ω 0 of the equation-of-state parameter of the dark energy. This model has the same number of free parameters as the ΛCDM model but it has no ΛCDM limit. We discuss the consistency between background observations and the mentioned stability-guaranteeing parameter combination.",
