Abstract
The biwarped product submanifolds generalize the class of product submanifolds and are particular case of multiply warped product submanifolds. The present paper studies the biwarped product submanifolds of the type S-T x psi S-1(perpendicular to) x(psi 2) S-theta in Sasakian space forms (S) over bar (c), where S-T, S-perpendicular to, and S-theta are the invariant, anti-invariant, and pointwise slant submanifolds of (S) over bar (c). Some characterizing inequalities for the existence of such type of submanifolds are proved; besides these inequalities, we also estimated the norm of the second fundamental form.
