A subclass of strongly close-to-convex functions associated with Janowski function [PDF]

Mathematical Journal of Okayama University
The aim of this paper is to introduce a new subclass of strongly close-to-convex functions by subordinating to Janowski function. Certain properties such as coefficient estimates, distortion theorem, argument theorem, inclusion relations and radius of convexity are established for this class.

Starlikeness of janowski spirallike functions in the unit disk

Online Journal of Analytic Combinatorics, 2023
The aim of this paper is to introduce and study a new class of analytic functions which generalize the classes of \(\lambda\)-Spirallike Janowski functions. In particular, we gave the representation theorem, the right side of the covering theorem, starlikeness estimates and some properties related to the functions in the class \( S_\lambda ( T, H, F ) \

Janowski Type q-Convex and q-Close-to-Convex Functions Associated with q-Conic Domain

Mathematics, 2020
Certain new classes of q-convex and q-close to convex functions that involve the q-Janowski type functions have been defined by using the concepts of quantum (or q-) calculus as well as q-conic domain

Variability regions for Janowski convex functions

Complex Variables and Elliptic Equations, 2012
In this study, regions of variability {log f′(z 0): f ∈ C λ[A, B]} are explicitly determined for the class C[A, B] of Janowski convex functions.

Radius of Limaçon starlikeness for Janowski starlike functions

Asian-European Journal of Mathematics, 2021
Let [Formula: see text] be an analytic function defined on the open unit disc [Formula: see text], with [Formula: see text], satisfying the subordination [Formula: see text], where [Formula: see text]. The domain [Formula: see text] is bounded by a Limaçon and the function [Formula: see text] is called starlike function associated with Limaçon domain.
