Subordination Properties for Certain Subclasses of Prestarlike Functions

Some Properties of Certain Subclasses of Close-to-Convex and Quasi-convex Functions with Respect to 2k-Symmetric Conjugate Points

On some applications of the Dziok-Srivastava operator

Carlson and Shaffer [B.C. Carlson, D.B. Shaffer, Starlike and prestarlike hypergeometric functions, SIAM J. Math. Anal. 15 (1984) 737–745] have introduced a linear operator associated with the Gaussian hypergeometric function which has been generalized by Dziok and Srivastava [J. Dziok, H.M. Srivastava, Classes of analytic functions associated with the generalized hypergeometric function, Appl....

Applications of multivalent prestarlike functions

Keywords: Analytic functions Multivalent prestarlike function Linear operator Hadamard product Subordination a b s t r a c t In the paper we introduce general classes of multivalent analytic functions defined by the subordination. In particular, we define the class of multivalent prestarlike functions. By using the Ruscheweyh's duality theory we investigate convolution properties related to mul...

A Unified Treatment of Certain Subclasses of Prestarlike Functions

In this paper we introduce and study some properties of a unified class U [μ, α, β, γ, λ, η, A,B] of prestarlike functions with negative coefficients in a unit disk U . These properties include growth and distortion, radii of convexity, radii of starlikeness and radii of close-to-convexity.

Subordination Properties for New Certain Subclasses of Univalent Functions

In this paper, we obtain some subordination results for certian subclasses of univalent functions defined by convolution.
