Systems of vectors and vectorial pairs of rays

Abstract

In previous works, I developed a vector system in detail. But since vectors essentially represent pairs of points, albeit unequal (initial and terminal) and since correlative rays can be established for each point, it is clear that systems of vectors can be correlative to systems of pairs of rays that can hardly be called anything other than vectorial. But if it is somewhat difficult to talk about vectorial pairs of rays on a plane, then, for the sake of complete clarity, I prefer to establish such a sequence of systems that are part of all the linear elements of this system.
