I sporadically work on this monograph in which I systematically use Vieta's formulas in order to categorize the geodesic trajectories of massive and massless particles in the geometry of some well-known black hole solutions. At the moment, I have only considered Schwarzschild and Kerr solutions (the latter not yet completely).
