The notion of differential superordination was introduced by Miller and Mocanu [3] as a dual concept of differential subordination [2] and was developed in [4]. The notion of strong differential subordination was introduced by Antonin and Romaguera [1]. The notion was developed in [8], [9], [10]. In [5] the author introduced the dual concept of strong differential superordinations. In this paper, a Briot-Bouquet strong differential superordination is studied.
