Description
We show that a variety of non-Keplerian galaxy rotation curves, together with the corresponding modifications of the Newtonian potential and dynamics, including MOND, qMOND, and mMOND-type behaviors, can be derived for test particles propagating on a background quantum geometry associated with a fluctuating spin connection, as described by precanonical quantum gravity (pQG).
In particular, we identify a quantum gravitational origin of Milgromian dynamics and derive a relation between the Milgromian acceleration scale $a_0$ and the cosmological constant. The smallness of these quantities is traced back to the precanonical quantization scale $\varkappa$, which enters the formulation of precanonically quantized Einstein--Yang--Mills theory and appears in estimates of the mass gap in quantum Yang--Mills theory.
These results suggest that pQG provides a first-principles framework for describing the very weak-field regime of galactic dynamics, offering a theoretically motivated alternative to phenomenological dark matter models and modified gravity scenarios.
