A note on F-sectional curvatures of S-manifolds
(Real Academia de Ciencias de Zaragoza, 1987)
This paper presents sorne characterizations of S-manifolds whose invariant f- sectional curvature is constant. The antiinvariant f-sectional curvature, the axiom of invariant f-planes and the axiom of antiinvariant f-planes ...

On totally geodesic invariant submanifolds of an S-manifold
(Real Academia de Ciencias de Zaragoza, 1988)
In [1] Blair, O.E.: 1970, J. Diff. Geom. 4, (155-167), S-manifolds, which reduce in a special case to Sasakian manifolds, we redefined. In this note, a condition for an invariant submanifold of codimension greater than 2 ...
