In the present article, we have investigated pointwise pseudo-slant
submanifolds of Kenmotsu manifolds and have sought conditions under which
these submanifolds are warped products. To this end first, it is shown that
these submanifolds can not be expressed as non-trivial doubly warped product
submanifolds. However, as there exist non-trivial (single) warped product
submanifolds of a Kenmotsu manifold, we have worked out characterizations in
terms of a canonical structure T and the shape operator under which a
pointwise pseudo slant submanifold of a Kenmotsu manifold reduces to a
warped product submanifold.
