Quasiconformal Harmonic Mappings Related to Janowski Starlike Functions
Sains Malaysiana, 2014 Let f(z) = h(z) + be a univalent sense-preserving harmonic mapping of the open unit disc D = {z vertical bar vertical bar z vertical bar < 1}. If f satisfies the condition vertical bar omega(z)vertical bar= vertical bar g'(z)/h'(z)vertical bar< k, 0 < k < 1, then is called k-quasiconformal harmonic mapping in D.

On Janowski Type Harmonic Meromorphic Functions with respect to Symmetric Point
Journal of Function Spaces, 2021 In this paper, we define a new class of Sakaguchi type-meromorphic harmonic functions in the Janowski domain that are starlike with respect to symmetric point.

Geometric Characteristics of Specific Classes Associated with q-Janowski Functions
AxiomsIn this paper, we integrate the concepts of spiral-like functions and Janowski-type functions within the framework of q-calculus to define new subclasses in the open unit disk.

The Schwarzian norm estimates for Janowski convex functions [PDF]
Proceedings of the Edinburgh Mathematical Society, 2022 AbstractFor $-1\leq B \lt A\leq 1$, let $\mathcal{C}(A,B)$ denote the class of normalized Janowski convex functions defined in the unit disk $\mathbb{D}:=\{z\in\mathbb{C}:|z| \lt 1\}$ that satisfy the subordination relation $1+zf''(z)/f'(z)\prec (1+Az)/(1+Bz)$. In the present article, we determine the sharp estimate of the Schwarzian norm for functions

Regions of Variability for Janowski Functions [PDF]
Miskolc Mathematical Notes, 2015 Summary: Let \(A\in \mathbb{C},\) \(B\in [ -1,0)\). Then \(P\left[ A,B\right] \) denotes the class of analytic functions \(p\) in the open unit disk with \(p\left( 0\right) =1\) such that \[ p\left( z\right) =\frac{1+Aw\left( z\right)}{1+Aw\left( z\right)}, \] where \(w\left( 0\right) =0\) and \(\left| w\left( z\right) \right|

Bohr Radius Problems for Some Classes of Analytic Functions Using Quantum Calculus Approach
Mathematics, 2020 The main purpose of this investigation is to use quantum calculus approach and obtain the Bohr radius for the class of q-starlike (q-convex) functions of order α . The Bohr radius is also determined for a generalized class of q-Janowski starlike and

q-Meromorphic closed-to-convex functions related with Janowski function
Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2022 Summary: In the present paper, we introduce and explore certain new classes of meromorphic functions related with closed-to-convexity and \(q\)-calculus. Such results as coefficient estimates, grow the property and partial sums are derived. It is important to mentioned that our results are generalization of number of existing results in literature.
