The Plane-Time in Which Paths of Inertional Motions Are Conics

Marko D. Leko

The Schwarzschild's solution gives, for 2-paths of particles, lines which are not conics. It gives, as a consequence, a precession efect. This paper is an attempt to find sucha metrics of the plane-time in the general theory of relataivity that 2-paths of particles be conics, without precessions.
