ON CERTAIN CLASSES OF P-VALENT FUNCTIONS DEFINED BY MULTIPLIER TRANSFORMATION AND DIFFERENTIAL OPERATOR
In this paper, we discuss the p-valent functions that satisfy the differential subordinations z(Ip(r,λ)f(z))(j+1) (p−j)(Ip(r,λ)f(z))(j) ≺ a+(aB+(A−B)β)z a(1+Bz) . We also obtain coefficientExpand

A Class Of Starlike Functions
In terms of Wright generalized hypergeometric function we define a class of analytic functions. The class generalize well known classes of k-starlike functions andk-uniformly convex functions.Expand

A new subclass of uniformly convex functions and a corresponding subclass of starlike functions with fixed second coefficient.
Making use of Linear operator theory, we define a new subclass of uniformly convex functions and a corresponding subclass of starlike functions with negative coefficients. The main object of thisExpand

CERTAIN CLASSES OF ANALYTIC FUNCTIONS WITH NEGATIVE COEFFICIENTS ASSOCIATED WITH A CONVOLUTION STRUCTURE
Making use of a convolution structure, we introduce a new class of analytic functions PTg(λ,α,β,γ) defined in the open unit disc and investigate its various characteristics. Further we obtainedExpand

STARLIKENESS OF MULTIVALENT MEROMORPHIC HARMONIC FUNCTIONS
We give sufficient coefficient conditions for starlikeness of a class of complex-valued multivalent meromorphic harmonic and orientation preserving functions in outside of the unit disc. TheseExpand

Subordination Results for Spirallike Functions
In this paper, we introduce a new class of functions which is defined by Dziok- Srivastava operator and obtain the subordination results for this class of functions. Some known and new results, whichExpand

Certain Subclasses of Starlike Functions of Complex Order Involving Generalized Hypergeometric Functions
TLDR
We define a new subclass of uniformly convex functions and a corresponding subclass of starlike functions with negative coefficients and obtain coefficient estimates, extreme points, the radii of close-to-convexity, starlikeness and convexity. Expand

On certain subclasses of analytic functions associated with hypergeometric functions
TLDR
We find the necessary and sufficient conditions for functions z F ( a , b ; c ; z ) in the generalized class of β uniformly starlike and β uniformly convex functions of order α. Expand

NEIGHBOURHOODS AND PARTIAL SUMS OF STARLIKE FUNCTIONS BASED ON RUSCHEWEYH DERIVATIVES
In this paper a new class S p (, ) of starlike functions is introduced. A subclass TS p (, ) of S p (, ) with negative coefficients is also considered. These classes are based on RuscheweyhExpand
