Linear Combinations of Harmonic Univalent Mappings
Many properties are known about analytic functions, however the class of harmonic functions which are the sum of an analytic function and the conjugate of an analytic function is less understood.

The radius of convexity of certain analytic functions II
In [2], MacGregor found the radius of convexity of the functions f(z)=z+a2z2+a3z3+…, analytic and univalent such that |f′(z)−1|

A function f(z) is said to be univalent in a region G if and only if f(z1) = f(s2 ) in G implies z1 = z2 whenever z1 and z2 are any two points in G. Another way of stating this is that a univalent function in G is characterized by the fact that it takes ...

Subclasses of Bi-Univalent Functions Defined by Frasin Differential Operator
Let Ω denote the class of functions f ( z ) = z + a 2 z 2 + a 3 z 3 + ⋯ belonging to the normalized analytic function class A in the open unit disk U = z : z < 1 , which are bi-univalent in U , that ...

On Use of Meijer's G-functions In The Theory of Univalent Functions [PDF]
Using some properties of Meijer's G-functions and univalent functions, in this paper some definitions, transformations and theorems in univalent function theory are discussed and then reformulated in the language of Meijer's G-functions.

Properties of a Linear Operator Involving Lambert Series and Rabotnov Function
This work is an attempt to apply Lambert series in the theory of univalent functions. We first consider the Hadamard product of Rabotnov function and Lambert series with coefficients derived from the arithmetic function σn to introduce a normalized ...
