Warped Product Pointwise Semi-slant Submanifolds of Nearly Kaehler Manifolds}

Abstract

In this paper, we study warped pointwise semi-slant submanifolds of nearly Kaehler manifolds. We prove that there  do not exist non-trivial warped
product pointwise semi-slant submanifolds of the form $N_\theta\times_fN_T$ in a nearly Kaehler manifold $\bar M$ but the geometry of warped products by reversing these two factors is similar to the case of general slant fiber.
