Abstract
The form of “gravitation”'s law in “projective relativity” is examined, based on a suitable generalization of Poisson's equation in de Sitter space-time; it is found that, in the interior case, a small difference with the customary Newtonian law arises. This difference, of a repulsive character, can be very important in cosmological problems.
