Abstract

In this paper, we introduce new concept that is fourth-order differential subordination and superordination associated with linear operator for univalent analytic functions in open unit disk. Here, we extended some lemmas. Also some interesting new results are obtained.

Keywords

Fourth-order, Differential subordination, Univalent function, Admissible function.
