Varying Gravity from a Modified Fractional Model: Observational Constraints and Slow-Fast Dynamics
Rami Ahmad El-Nabulsi, Genly Leon, Esteban González +1
We investigate a fractional gravity model in which both the Hubble parameter and the gravitational constant evolve dynamically due to fractional renormalization-group effects. The…

Fractional Einstein-Gauss-Bonnet scalar field cosmology
Bayron Micolta-Riascos, Alfredo D. Millano, Genly Leon +3
Our paper introduces a new theoretical framework called the Fractional Einstein--Gauss--Bonnet scalar field cosmology, which has important physical implications. Using fractional c…
