On certain anti-invariant submanifolds of an S-manifold
(Sociedade Portuguesa de Matemática, 1993)In this paper, the geometry of certain anti-invariant submanifolds of an S-manifold, namely those which are normal to the structure vector fields, is studied.

CR-products of S-manifolds
(Sociedade Portuguesa de Matemática, 1990)In this paper certain CR-submanifolds namely the CR-products, are studied. A characterization theorem is given and the case of CR-products of S-manifolds whose invariant f-sectional curvature is constant, is investigated.
