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…

Do time delay effects explain galactic velocity profiles?
L. Benkoula, K. Chima, J. Kingsbury +3
Using the gravitoelectromagnetic analogy for weak gravitational fields, we critique explanations of galactic velocity profiles that invoke time delay effects (i.e. "retarded gravit…

Conformal and Non-Minimal Couplings in Fractional Cosmology
Kevin MarroquÃn, Genly Leon, Alfredo D. Millano +2
Fractional differential calculus is a mathematical tool that has found applications in the study of social and physical behaviors considered ``anomalous''. It is often used when tr…
