Q-Extension of Starlike Functions Subordinated with a Trigonometric Sine Function
, 2020 The main purpose of this article is to examine the q-analog of starlike functions connected with a trigonometric sine function. Further, we discuss some interesting geometric properties, such as the well-known problems of Fekete-Szegö, the necessary

On a subclass of Bazilevič functions
International Journal of Mathematics and Mathematical Sciences, 1985 Let B(α) be the class of normalised Bazilevič functions of type α>0 with respect to the starlike function g. Let B1(α) be the subclass of B(α) when g(z)≡z. Distortion theorems and coefficient estimates are obtained for functions belonging to B1(α).

New Properties of Analytic Functions
MathematicsIn the present paper, we consider the class A¯ of functions f(z) of the form f(z)=z+∑k=1∞a1+k3z1+k3 that are analytic in the open unit disc U. If a1+k3=0 for k≠3n(n=1,2,3,⋯), then f(z) is given by f(z)=z+∑k=2∞akzk.

ON A CHARACTERIZATION OF THE CLASS OF STARLIKE UNIVALENT FUNCTIONS
, 2014 Dedicated to Maxwell O. Reade on the occasion of his retirement. 1. Introduction. Let S be the class of functions f(z) = z + 232 anZ which are regular and univalent in the unit disc D = { z: {zl < 1}. By S*, S*(cr) and SP(cr) we denote the subclasses

Certain subclasses of k-uniformly starlike functions associated with symmetric q-derivative operator
, 2018 In this paper, we have established the inclusion relations for k-uniformly starlike functions under the (Dqf)(z) operator. We define two new subclass of k-uniformly starlike functions of order α.

Starlike functions associated with the generalized Koebe function [PDF]
In this paper we study some properties of functions f which are analytic and normalized (i.e. f (0) = 0 = f' (0) - 1) such that satisfy the following subordination relation(zf'(z)/f(z) - 1) < z/ (1 - pz)(1 - qz),where (p, q) is an element of [-1, 1] x ...
