Query: Geodesic Structure of the Noncommutative Schwarzschild Anti-de Sitter
  Black Hole I: Timelike Geodesics   By considering particles as smeared objects, we investigate the effects of
space noncommutativity on the geodesic structure in Schwarzschild-AdS
spacetime. By means of a detailed analysis of the corresponding effective
potentials for particles, we find the possible motions which are allowed by the
energy levels. Radial and non-radial trajectories are treated and the effects
of space noncommutativity on the value of the precession of the perihelion are
estimated. We show that the geodesic structure of this black hole presents new
types of motion not allowed by the Schwarzschild spacetime.
