AbstractLet q1 and q2 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 q1(z)≺p(z)≺q2(z). The differential sandwich-type result obtained is applied to normalized univalent functions and to Φ-like functions
