In the emergent cosmic space scenario recently proposed by Padmanabhan, the expansion of the universe is attributed to the difference between the number of degrees of freedom on a holographic surface and the one in the bulk. Based on this idea, we explore the cases where logarithmic and power-law entropic corrections are present, respectively. The previously found modified Friedmann equations are reproduced through an improved proposal, and we show that the same results can be obtained using a generalized expansion law.

Observational Constraints on Emergent Fractional Fractal Cosmology
Joint SN+H(z)+fσ8+BAO+CMB analysis constrains the EFF fractal dimension to d=2.0004^{+0.0006}_{-0.0003}, with BIC favoring plain ΛCDM.
