We investigate the new class H b (α, β) of analytic functions with Koebe type. The subordination, superordination, best dominant result for that class was obtain. And by making use of Jack's Lemma as well as several differential and other inequalities, the authors derive sufficient conditions for starlikeness of the class H b (α, β) of n-fold symmetric analytic functions of Koebe type. Relevant...

In this paper, the author combines geometric theory of analytic function regarding differential superordination and subordination with fuzzy for convolution product Ruscheweyh derivative multiplier transformation. Interesting inequalities are obtained by author.

Strong dierential subordination and superordination properties are determined for some familiesanalytic functions in the open unit disk which are associated with the Komatu operator by investigatingappropriate classes of admissible functions. New strong dierential sandwich-type results arealso obtained.

In this paper, we discuss and introduce a new study using an integral operator wk,μm in geometric function theory, especially sandwich theorems. We obtained some conclusions for differential subordination superordination formula generalized operator. addition, certain theorems were found. The theory’s features outcomes are symmetric to those derived the theory.

In present paper, we use fractional integral and Wanas differential operator to obtain some subordination superordination results associated with Hadamard product for univalent analytic functions defined in the open unit disk. These are applied sandwich results. Our extend corresponding previously known

The notion of strong differential subordination was introduced in 1994 and the theory related to it developed 2009. dual superordination also In a paper published 2012, given new approach by defining classes analytic functions on U×U¯ having as coefficients holomorphic U¯. Using those classes, extended S?l?gean Ruscheweyh operators were operator defined L?m:An?*?An?*,L?mf(z,?)=(1??)Rmf(z,?)+?Sm...

The purpose of this paper is to derive subordination and superordination results involving differential operator for multivalent analytic functions in the open unit disk. These are applied obtain sandwich results. Our extend corresponding previously known
