چکیده
Abstract Lightlike hypersurfaces in semi-Riemannian manifolds admitting concircular vector fields are investigated. We prove that such generally products of lightlike curves and warped product manifolds. In special cases, we show these totally geodesic or screen provided belong to their normal transversal bundles. A number examples furnished, where possible, illustrate the main concepts.

Lightlike hypersurfaces in indefinite S-manifolds
In a metric g.f.f -manifold we study lightlike hypersurfaces M tangent to the characteristic vector fields, and owing to the presence of the f -structure, we determine some decompositions of TM and of a chosen screen distribution obtaining two distributions invariant with respect to the structure. We discuss the existence of a g.f.f -structure on a lightlike hypersurface and, under suitable hyp...

متن کاملThe curvatures of lightlike hypersurfaces of an indefinite Kenmotsu manifold
We study the forms of curvatures of lightlike hypersurfaces M of an indefinite Kenmotsu manifold M̄ subject to the conditions: (1) M is locally symmetric, i.e., the curvature tensor R of M be parallel on TM , or (2) M is a semi-symmetric manifold, i.e., R(X, Y )R = 0 on TM .

متن کاملHypersurfaces in weighted projective spaces over finite fields with applications to coding theory
We consider the question of determining the maximum number of Fqrational points that can lie on a hypersurface of a given degree in a weighted projective space over the finite field Fq, or in other words, the maximum number of zeros that a weighted homogeneous polynomial of a given degree can have in the corresponding weighted projective space over Fq. In the case of classical projective spaces...
متن کاملOn Concircular and Torse-forming Vector Fields on Compact Manifolds
In this paper we modify the theorem by E. Hopf and found results and conditions, on which concircular, convergent and torse-forming vector fields exist on (pseudo-) Riemannian spaces. These results are applied for conformal, geodesic and holomorphically projective mappings of special compact spaces without boundary.
