Resumen de On the symmetries of the Lorentzian oscillator group

Giovanni Calvaruso, Amirhesam Zaeim

• We consider the four-dimensional oscillator group, equipped with a well known one-parameter family of left-invariant Lorentzian metrics. We obtain a full classification of its Ricci (curvature, Weyl) collineations and matter collineations, and also point out the left-invariant collineations.
