Curvature properties of $ϕ$ -null Osserman Lorentzian $S$ -manifolds

Letizia Brunetti, Angelo V. Caldarella

We expound some results about the relationships between the Jacobi operators with respect to null vectors on a Lorentzian $S$ -manifold $M$ and the Jacobi operators with r…

An Osserman-type condition on $g . f . f$ -manifolds with Lorentz metric

Letizia Brunetti

A condition of Osserman type, called $ϕ$ -null Osserman condition, is introduced and studied in the context of Lorentz globally framed $f$ -manifolds. An explicit example shows the n…
