Title: Warped Product Pointwise Semi-slant Submanifolds of Sasakian Manifolds,
Abstract: Recently, B.-Y. Chen and O. J. Garay studied pointwise slant submanifolds of
almost Hermitian manifolds. By using this notion, we investigate pointwise
semi-slant submanifolds and their warped products in Sasakian manifolds. We
give non-trivial examples of such submanifolds and obtain several fundamental
results, including a characterization for warped product pointwise semi-slant
submanifolds of Sasakian manifolds.
