New Results on a Fractional Integral of Extended Dziok–Srivastava Operator Regarding Strong Subordinations and Superordinations

In 2012, new classes of analytic functions on U×U¯ with coefficient holomorphic in U¯ were defined to give a approach the concepts strong differential subordination and superordination. Using those classes, extended Dziok–Srivastava operator is introduced this paper and, applying fractional integral operator, we obtain Dz−γHmlα1,β1 that was not previously studied using subordinations superordinations. present article, applied investigated by means superordination theory same U×U¯. Several superordinations concerning are established, best dominant subordinant given for each superordination, respectively. This may have symmetric or asymmetric properties.
