Some relations including various linear operators

100%

Dziok J.

2007

tom Vol. 40, nr 1

77-84

Making use of the Carlson-Schaer linear operator, some subclasses of analytic functions are studied. Some relations including various linear operators are given.

Classes of p-valent analytic function

100%

Dziok J.

tom Vol. 33, nr 1

55-63

Some parametric family of functions

100%

Dziok J.

tom Vol. 29

99-107

In the paper, we define classes of analytic functions, in terms of some linear operator. Coefficients estimates, distortion theorems, and the radii of convexity and starlikeness for this class of analytic functions are given here.

Certain operators and inequalities and their applications to meromorphically multivalent functions

tom Vol. 36, nr 4

839--846

In the present paper, making use of certain operators, some theorems involving inequalities on meromorphically multivalent functions in the punctured unit disk are obtained. Moreover, some of the results which are important for geometric function theory are also included.

Aouf M. K. , Dziok J.

tom Vol. 30

23-32

Using the Wrigh's generalized hypergeometric function, we introduce a new class W(q, s; A, B, γ) of analytic functions with nega-tive coefficients. In this paper we investigate coefficient estimates, distortion theorem and the radii of convexity and starlikeness.

Classes of functions defined by subordination

63%

Dziok J. , Stankiewicz J.

tom Vol. 30

53-59

In the paper, we define classes of analytic functions, in terms of subordination. We present some inclusion relations for defined classes.

Distortion and convolutional theorems for operators of generalized fractional calculus involving wright function

63%

Aouf M. K. , Dziok J.

tom Vol. 14, nr 2

183-192

Using the Wright's generalized hypergeornetric function, we investigate a class W(q,s: A, B, λ) of analytic functions with negative coefficients. We derive many results for the modified Hadamard product of functions belonging to the class W(q,s: A, B, λ) . Moreover, we generalize some of the distortion theorems to the classical fractional integrals and derivatives and the Saigo (hypergeornetric) operators of fractional calculus.

tom Vol. 29

109-120

The main object of the present paper is to investigate several results of certain differential operators which were recently introduced and (or) studied in a series of papers by Chen et et al. [1-3], Irmak et al. [8, 10, 11], Dziok et al. [5, 6] and Liu et al. [14]. In addition, some applications of our results involving certain differential inequalities of multivalently analytic and (or) multivalently raeromorphic functions are given. Our certain results also include some recent results in [5, 6, 9, 11, 12].
