on geometry of warped product semi invariant submanifolds of nearly (ε, δ)-trans sasakian manifold with a certain connection

In this paper, we study the geometry of warped product semi invariant submanifold of a nearly ( epsilon;, delta;)-trans-sasakianmanifold m with a quarter symmetric non metric connection. we see that warped product of the typee perp; ×yet is a usual riemannian product of e perp; and et , where e perp; and et are anti-invariant and invariant submanifolds of a nearly ( epsilon;, delta;)-trans-sasakian manifold with a quarter symmetric non metric connection m, respectively. we also obtain a characterization for such type of warped product.
