Fractional cosmology modifies density perturbation growth via parameter α, yielding a new upper bound α ≲ 1.07 from σ8 normalization and Sachs-Wolfe constraints.
Fractional cosmology produces emergent inflation as a stable attractor from a non-singular pre-inflationary regime, with the number of e-folds related to the fractional parameter α and a subsequent radiation-dominated era.
