Radii of Starlikeness Associated with the Lemniscate of Bernoulli and the Left-Half Plane
, 2011 A normalized analytic function f defined on the open unit disk in the complex plane is in the class SL if zf'(z)/f(z) lies in the region bounded by the right-half of the lemniscate of Bernoulli given by |w^2 - 1| < 1. In the present investigation, the SL-

On an extension of Sakaguchi's result
, 2015 We improve Pommerenke’s result [15] by using a generalized lemma from [11]. It gives an extension of Sakaguchi’s result too, [18]. Several applications of main theorems are presented. A part of them improves the previous results of this type. We consider

New Coefficient Conditions for Functions Starlike with Respect to Symmetric Points [PDF]
, 2010 2000 Mathematics Subject Classification: Primary 30C45, secondary 30C80.We consider some familiar subclasses of functions starlike with respect to symmetric points and obtain sufficient conditions for these classes in terms of their Taylor coefficient ...

Some properties of a class of holomorphic functions associated with tangent function
Demonstratio MathematicaIn this study, we define new class of holomorphic functions associated with tangent function. Furthermore, we examine the differential subordination implementation results related to Janowski and tangent functions. Also, we investigate some extreme point

Prescribing the Preschwarzian in several complex variables
, 2010 We solve the several complex variables preSchwarzian operator equation $[Df(z)]^{-1}D^2f(z)=A(z)$, $z\in \C^n$, where $A(z)$ is a bilinear operator and $f$ is a $\C^n$ valued locally biholomorphic function on a domain in $\C^n$.

Applications of the Owa-Srivastava Operator to the Class of K-Uniformly Convex Functions [PDF]
, 2006 2000 Mathematics Subject Classification: Primary 30C45, 26A33; Secondary 33C15By making use of the fractional differential operator Ω^λz (0 ≤ λ < 1) due to Owa and Srivastava, a new subclass of univalent functions denoted by k−SPλ (0 ≤ k < ∞) is ...

Concave univalent functions and Dirichlet finite integral
, 2016 The article deals with the class ${\mathcal F}_{\alpha }$ consisting of non-vanishing functions $f$ that are analytic and univalent in $\ID$ such that the complement $\IC\backslash f(\ID) $ is a convex set, $f(1)=\infty ,$ $f(0)=1$ and the angle at ...
