Rotational velocity fields of galaxies and projective geometry of spacetime
Abstract
Relativistic localizing systems show that the pseudo-Riemannian geometry of spacetime is somehow encapsulated in the projective geometry of a Cartan connection space (generalized Cartan space). In this paper, we present fits of rotational velocity fields of galaxies based on a modification of the Newton's law of gravitation such that it becomes equivariant with respect to the homographic transformations induced by this projective geometry.
