Study on a subclass of holomorphic functions associated to the q-analogue multiplier transformation defined in a Janowski domain

Miskolc Mathematical Notes
The present study uses differential subordination in conjunction with Janowski-type functions to establish the particular class F(m,n,λ,q,D,E)q𝒢−1𝒢∈F(m,n,λ,q,D,E)F(m,n,λ,q,D,E ...

Some Properties of a Generalized Class of Analytic Functions Related with Janowski Functions

Abstract and Applied Analysis, 2012
We define a class [A, B, α, ρ] of analytic functions by using Janowski’s functions which generalizes a number of classes studied earlier such as the class of strongly close‐to‐convex functions. Some properties of this class, including arc length, coefficient problems, and a distortion result, are investigated.

Schwarzian derivative and Janowski convexity [PDF]

, 2017
Sufficient conditions relating the Schwarzian derivative to the Janowski convexity of a normalized analytic function f are obtained. As a consequence, sufficient conditions are determined for the function f to be Janowski convex and convex of order α ...

Coefficient inequalities for $q$-starlike functions associated with the Janowski functions

Hokkaido Mathematical Journal, 2019
The main purpose of this investigation is to find several coefficient inequalities and a sufficient condition for $q$-starlike functions which are associated with the Janowski functions. Relevant connections of the results presented in this paper with those in a number of other related works on this subject are also pointed out.

Harmonic functions with varying coefficients

Journal of Inequalities and Applications, 2016
Complex-valued harmonic functions that are univalent and sense preserving in the open unit disk can be written in the form f = h + g ‾ $f=h+\overline{g}$ , where h and g are analytic.

Coefficient Bounds for q-Noshiro Starlike Functions in Conic Region

Journal of Function Spaces
We present and examine a new family of analytic functions that can be described by a q-Ruscheweyh differential operator. We discuss several novel results, including coefficient inequalities and other noteworthy properties such as partial sums and radii ...
