Some Properties for an Integral Operator Defined by Al-oboudi Differential Operator

In this paper, we investigate some properties for an integral operator defined by Al-Oboudi differential operator.

A new univalent integral operator defined by Al - Oboudi differential operator 1 Serap Bulut

In [3], Breaz and Breaz gave an univalence condition of the integral operator Gn,α introduced in [2]. The purpose of this paper is to give univalence condition of the generalized integral operator Gn,m,α defined in [4]. Our results generalize the results of [3]. 2000 Mathematics Subject Classification: 30C45.

Sufficient Conditions for Univalence of an Integral Operator Defined by Al-Oboudi Differential Operator

Coefficient Estimates for Initial Taylor-Maclaurin Coefficients for a Subclass of Analytic and Bi-Univalent Functions Defined by Al-Oboudi Differential Operator

We introduce and investigate an interesting subclass NP(λ,δ)(Σ) (n, β; h) of analytic and bi-univalent functions in the open unit disk U. For functions belonging to the class NP(λ,δ)(Σ) (n, β; h), we obtain estimates on the first two Taylor-Maclaurin coefficients |a₂| and |a₃|.

AN INTEGRAL UNIVALENT OPERATOR DEFINED BY GENERALIZED Al-OBOUDI DIFFERENTIAL OPERATOR ON THE CLASSES Tj, Tj,μ AND Sj(p)

In [4], Breaz and Breaz gave the univalence conditions of the integral operator Fα,n of the analytic functions belonging to the classes T2, T2,μ and S(p). The purpose of this paper is to generalize the integral operator Fα,n by means of the generalized Al-Oboudi differential operator and investigate univalence conditions of this generalized integral operator considering the classes Tj , Tj,μ an...
