In the fractional model, matter density perturbations grow as t^{p±(α)} and matching the late-time growth to σ8 yields α≲1.07.
By choosing an α-dependent gravitational potential, fractional Newtonian cosmology reproduces radiation-, matter-, and dark-energy-dominated expansion, with an effective cosmological constant set by |1−α|.
