abstract

We employ Riesz's fractional derivative into the Wheeler--DeWitt equation for a closed de Sitter geometry and obtain the no-boundary and tunneling wavefunctions. From the corresponding probability distributions, the event horizon of the nucleated universe can be a fractal surface with dimensions between $2\leq D<3$. Concretely, the tunneling wavefunction favors fractal dimensions less than $2.5$ and an accelerated power-law phase. Differently, the no-boundary proposal conveys fractal dimensions close to $3$, with the universe instead entering a decelerated phase. Subsequently, we extend our discussion towards (non-trivial compact) flat and open scenarios. Results suggest that given the probability of creation of a closed inflationary universe in the tunneling proposal is exponentially suppressed, a flat or an open universe becomes favored within fractional inflationary quantum universe.

  1. Cosmological consequences of scale-dependent Barrow-Tsallis entropy

    gr-qc 2026-07 conditional novelty 6.0 of 10

    A scale-dependent Barrow-Tsallis entropy cosmology fits cosmic data but is statistically disfavored versus ΛCDM, with only a modest and partially circular Hubble-tension 'alleviation'.

  2. Fractional entropy of the Brown-Kucha\v{r} dust in fractional anti-de Sitter quantum gravity

    gr-qc 2025-01 conditional novelty 5.0 of 10

    In flat AdS quantum cosmology with Brown-Kuchar dust, the fractional Wheeler-DeWitt equation yields mass and entropy spectra scaling as (n+1/2)^(alpha/2), with a fractal mass dimension D = 3 alpha / 2.

  3. Observational Constraints on Emergent Fractional Fractal Cosmology

    gr-qc 2026-07 conditional novelty 4.0 of 10

    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.

  4. Fractional Schwarzschild-Tangherlini black hole with a fractal event horizon

    gr-qc 2025-06 reject novelty 4.0 of 10

    A fractional Wheeler-DeWitt equation yields D-dimensional Schwarzschild-Tangherlini black holes, with the horizon called fractal and the temperature set by an arbitrary parameter alpha.
