Abstract
The main result we give in this brief note relates, under suitable hypotheses, the {\phi}-null Osserman, the null Osserman and the classical Osserman conditions to each other, via semi-Riemannian submersions as projection maps of principal torus bundles arising from a Lorentzian S-manifold.
