Fractional Differential Superordination

並列摘要


The notion of differential superordinationwas introduced by S.S.Miller and P.T. Mocanu as a dual concept of differential subordination. Recently, in Tamkang J. Math., the author have introduced the notion of fractional differential subordination. In this work, we consider the dual problem of determining properties of analytic functions that satisfy the fractional differential superordination. By employing some types of admissible functions, involving differential operator of fractional order, we illustrate geometric properties such as starlikeness and convexity for a class of analytic functions in the unit disk. Moreover, applications are posed in the sequel.
