摘要
.我们研究了独立肯莫特流形的全接触脐屏斜光样子流形和全接触脐屏横光样子流形。我们证明了独立建模流形的全接触脐屏斜光样子流形的特征定理。我们进一步证明了关于独立肯莫特流形的完全接触脐基屏横光似子流形的一些结果,如屏分布 S ( TM ) 可积分的必要和必要条件,以及诱导连接∇是一个度量连接的必要和必要条件。
Totally contact umbilical screen-slant and screen-transversal lightlike submanifolds
of indefinite Kenmotsu manifold
. We study totally contact umbilical screen-slant lightlike submanifolds and totally contact umbilical screen-transversal lightlike submanifolds of an indefinite Kenmotsu manifold. We prove a characterization theorem of totally contact umbilical screen-slant lightlike submanifolds of an indefinite Kenmotsu manifold. We further prove some results on a totally contact umbilical radical screen-transversal lightlike submanifold of an indefinite Kenmotsu manifold, such as the necessary and sufficient conditions for the screen distribution S ( TM ) to be integrable and for the induced connection ∇ to be a metric connection.
