Contact CR-warped product submanifolds of nearly Quasi-Sasakian manifold

In the present paper, we construct contact CR-warped product submanifolds of nearly quasi Sasakian manifold. We have obtained results on the existence of warped product CR Submanifolds of nearly quasi Sasakian manifold and discuss the characterization result. We also construct the inequality IIhII^2 >_ 2As+2sIIdel ln fII^2 for contact CR warped products of nearly quasi Sasakian manifolds. The equality cases are also discussed.本文中，我们构造了近拟Sasakian流形（nearly quasi Sasakian manifold）的接触CR-扭曲积子流形。我们得到了近拟Sasakian流形的扭曲积CR子流形的存在性相关结论，并对其刻画结果展开了讨论。此外，我们还针对近拟Sasakian流形的接触CR-扭曲积子流形，建立了不等式||h||² ≥ 2As + 2s||∇ln f||²，并对该不等式的等号成立情形进行了探讨。
