Abstract :
Let q 1 and q 2 belong to a certain class of normalized analytic univalent functions in the open unit disk of the complex plane. Sufficient conditions are obtained for normalized analytic functions p to satisfy the double subordination chain q 1 ( z ) ≺ p ( z ) ≺ q 2 ( z ) . The differential sandwich-type result obtained is applied to normalized univalent functions and to Φ -like functions.
