Abstract

To any globally framed f-manifold carrying a structure of S-manifold we associate several

indefinite S-manifolds. We determine the links between the corresponding Levi-Civita

connections and sectional curvatures. We state some local semi-Riemannian decomposition

theorems.

Keywords

Semi-Riemannian manifolds, indefinite metrics, Lorentz metrics, f-structures
