On a subfamily of starlike functions related to Hyperbolic Cosine function [PDF]
The Journal of Analysis, 2022 We introduce and study a new Ma–Minda subclass of starlike functions $${\mathcal {S}}^*_{\varrho },$$ S ϱ ∗ , defined as $$\begin{aligned} {\mathcal {S}}^{*}_{\varrho }:=\left\{ f\in {\mathcal {A}}:\frac{zf'(z)}{f(z)} \prec \cosh \sqrt{z}=:\varrho (z), z\

Hankel and Toeplitz determinant for a subclass of multivalent q-starlike functions of order α
AIMS Mathematics, 2021 In this paper our aim is to study some valuable problems dealing with newly defined subclass of multivalent $q$-starlike functions. These problems include the initial coefficient estimates, Toeplitz matrices, Hankel determinant, Fekete-Szego problem ...

A New Measure of Quantum Starlike Functions Connected with Julia Functions
Journal of Function Spaces, 2022 In a complex domain, the investigation of the quantum differential subordinations for starlike functions is newly considered by few research studies. In this note, we arrange a set of necessary conditions utilizing the concept of the quantum differential

Subclasses of uniformly starlike functions [PDF]
International Journal of Mathematics and Mathematical Sciences, 1992 We study subclasses of the class of uniformly starlike functions which were recently introduced by A.W. Goodman. One new subclass is defined and it is shown that it shares many properties of the parent class.
