Slant lightlike submanifolds of indefinite Kenmotsu manifolds
Degenerate metric Slant lightlike submanifolds Kenmotsu manifold
2011/4/6
In this paper, we introduce the notion of a slant lightlike submanifold of an indefinite Kenmotsu manifold. We provide a non-trivial example and obtain necessary and sufficient conditions for the exis...
Transversal lightlike submanifolds of indefinite sasakian manifolds
Indefinite Sasakian Manifold Lightlike Submanifold Radical Transversal Lightlike Submanifold Transversal Lightlike Submanifold
2010/12/21
We study both radical transversal and transversal lightlike submanifolds of indefinite Sasakian manifolds. We give examples, investigate the geometry of distributions and obtain necessary and sufficie...
Radical Anti-Invariant Lightlike Submanifolds of Semi-Riemannian Product Manifolds
Degenerate Metric Semi-Riemannian Product Manifold r-Lightlike Submanifold Locally Riemannian Product
2007/6/20
We introduce radical anti-invariant lightlike submanifolds of a semi Riemannian product manifold and give examples. After we obtain the conditions of integrability of distributions which are involved ...
