Subordination and Superordination Properties for Convolution Operator

In present paper a certain convolution operator of analytic functions is defined. Moreover, subordination and superordination- preserving properties for a class of analytic operators defined on the space of normalized analytic functions in the open unit disk is obtained. We also apply this to obtain sandwich results and generalizations of some known results.

A Note on Strong Differential Subordinations Using a Generalized Sălăgean Operator and Ruscheweyh Operator

In the present paper we establish several strong differential subordinations regardind the extended new operator DRm λ defined by the Hadamard product of the extended generalized Sălăgean operator Dm λ and the extended Ruscheweyh derivative Rm, given by DRm λ : Anζ → Anζ , DRm λ f (z, ζ) = (Dm λ ∗Rm) f (z, ζ) , where Anζ = {f ∈ H(U × U), f(z, ζ) = z + an+1 (ζ) zn+1 + . . . , z ∈ U, ζ ∈ U} is th...

Strong differential subordination and superordination of analytic functions associated with Komatu operator

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.

Certain Subclasses of Analytic Functions with Negative Coefficients Defined by Generalized Sălăgean Operator

Abstract We introduce the subclass Tj(n, m, γ, α, λ) of analytic functions with negative coefficients defined by generalized Sălăgean operator D λ . Coefficient estimates, some important properties of the class Tj(n, m, γ, α, λ) and distortion theorems are determined. Further, extremal properties and radii of close-to-convexity, starlikeness and convexity of the class Tj(n, m, γ, α, λ) are obta...
