Argument Estimates of Multivalent Functions Involving a Certain Fractional Derivative Operator

Argument Estimates of Certain Multivalent Functions Involving a Linear Operator

The purpose of this paper is to derive some argument properties of certain multivalent functions in the open unit disk involving a linear operator. We also investigate their integral preserving property in a sector.

Certain Subclass of Analytic and Multivalent Functions Defined by Using a Certain Fractional Derivative Operator

Making use of a certain operator of fractional derivative, a new subclass Fλ(n, p, α, μ) of analytic and p-valent functions with negative coefficients is introduced and studied here rather systematically. Coefficient estimates, a distortion theorem and radii of p-valently closeto-convexity, starlikeness and convexity are given. Finally several applications involving an integral operator and a c...

Properties of multivalent functions associated with certain integral operator

Let A(p) denote the class of functions which are analytic in the open unit disk U. By making use of certain integral operator,we obtain some interesting properties of multivalent analytic functions.

Certain Properties of Multivalent Functions Involving the Dziok-srivastava Operator

The object of the present paper is to investigate some subordination properties of multivalent analytic functions which are defined here by using the DziokSrivastava operator. Furthermore, relevant connections of the results presented in this paper with those obtained in earlier works are also discussed.
