Fractional-Dimension Gravity and the Milky Way Galaxy

Gabriele U. Varieschi

In this work, we focus our analysis of Fractional-Dimension Gravity (FDG) on our home galaxy, the Milky Way (MW), by using the latest Gaia DR3 data as well as previous rotation cur…

Newtonian Fractional-Dimension Gravity and the Mass-Dimension Field Equation

Gabriele U. Varieschi

We resume our analysis of Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model that does not require the dark matter (DM) paradigm. We add three more g…

Newtonian Fractional-Dimension Gravity and Galaxies without Dark Matter

Gabriele U. Varieschi

We apply Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model, to some notable cases of galaxies with little or no dark matter. In the case of the ultr…

Newtonian Fractional-Dimension Gravity and the External Field Effect

Gabriele U. Varieschi

We expand our analysis of Newtonian Fractional-Dimension Gravity (NFDG), an extension of the classical laws of Newtonian gravity to lower dimensional spaces, including those with f…

Gravitational potential and galaxy rotation curves in multi-fractional spacetimes

Gianluca Calcagni, Gabriele U. Varieschi

Multi-fractional theories with integer-order derivatives are models of gravitational and matter fields living in spacetimes with variable Hausdorff and spectral dimension, original…

Relativistic Fractional-Dimension Gravity

Gabriele U. Varieschi

This paper presents a relativistic version of Newtonian Fractional-Dimension Gravity (NFDG), an alternative gravitational model recently introduced and based on the theory of fract…
