Warped Product Submanifolds of Riemannian Product Manifolds

We study warped product of the type N θ × f N T and N θ × f N ⊥ , where N θ , N T , and N ⊥ are proper slant, invariant, and anti‐invariant submanifolds, respectively, and we prove some basic results and finally obtain some inequalities for squared norm of second fundamental form.
