In this paper, the class SH(α, β; n, λ) of univalent harmonic and sense-preserving mappings in the unit disk is introduced. The distortion inequalities and extreme points for functions in the class SH...
We consider the Fekete-Szeg\"o problem with real parameter $\lambda$ for the class $Co(\alpha)$ of concave univalent functions.
In the present paper, the authors introduce and study new subclass of normalized analytic univalent function S∗w (k, β) for some operator on Hilbert space.
In this paper by making use of the generalized Bernardi-Libera-Livingston integral operator we introduce and study some new subclasses of univalent functions. Also we investigate the relations between...
Subclass of univalent functions with negative coefficients and starlike with respect to symmetric and conjugate points
The class of univalent harmonic functions on the unit disc satisfying the condition is given. Sharp coefficient relations and distortion theorems are given for these functions. In this paper we fin...
Using the Salagean derivative, we introduce and study a class of Goodman-Ronning type harmonic univalent functions. We obtain coefficient conditions, extreme points, distortion bounds, convolution con...
The theory of harmonic univalent mappings has become a very popular research topic in recent years. The aim of this expository article is to present a guided tour of the planar harmonic univalent and ...
A necessary and sufficient coefficient is given for functions in a class of complex-valued harmonic univalent functions using the Dziok-Srivastava operator. Distortion bounds, extreme points, an integ...
On certain class of univalent functions with negative coefficients.
For λ ≥ 0, n ∈ N0, in [3], the authors introduced the operator Dn λ,which is a generalized Ruscheweyh derivatives operator. In this paper,some results on coefficient inequalities, growth and distortio...
