The main focus of this research is to solve certain coefficient-related problems for analytic functions that are subordinated to a unique trigonometric function. For the class S sin*, with …
In this study, by making the use of q-analogous of the hyperbolic tangent function and a Sălăgean q-differential operator, a new class of q-starlike functions is introduced. The prime …
The purpose of this article is to obtain the sharp estimates of the first four initial logarithmic coefficients for the class BT s of bounded turning functions associated with a petal-shaped …
The theory of univalent functions has shown strong significance in the field of mathematics. It is such a vast and fully applied topic that its applications exist in nearly every field of applied …
In our present study, two subclasses of starlike functions which are symmetric about the origin are considered. These two classes are defined with the use of the sigmoid function …

The present study's intention is to produce exact estimations of some problems involving logarithmic coefficients for functions belonging to the considered subcollection BT sin of the …
This study deals with analytic functions with bounded turnings, defined in the disk O d= z: z< 1. These functions are subordinated by sigmoid function 2 1+ e− z and their class is denoted …
One of the challenging tasks in the study of function theory is how to obtain sharp estimates of coefficients that appear in the Taylor–Maclaurin series of analytic univalent functions, and …
