      CR-products of S-manifolds 

      Fernández Fernández, Luis Manuel (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.

      Induced structures on slant submanifolds of metric F-manifolds 

      Fernández Fernández, Luis Manuel; Hans Uber, María Belén (Indian National Science Academy, 2008-10)
      We study whether it is possible to obtain an induced structure on a slant submanifold of a metric f-manifold. Moreover, ...

      On certain anti-invariant submanifolds of an S-manifold 

      Cabrerizo Jaraíz, José Luis; Fernández Fernández, Luis Manuel (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.
