چکیده
|
We study the geometry of lightlike submanifolds (m,g,s(tm),s(tm ⊥)) of a semi-riemannian manifold (m̃,g̃) of quasiconstant curvature subject to the following conditions: (1) the curvature vector field ζ of m̃ is tangent to m,(2) the screen distribution s (t m) of m is totally geodesic in m,and (3) the coscreen distribution s (t m ) of m is a conformal killing distribution. © 2012 d. h. jin and j. w. lee.
