Rocky Mountain Journal of Mathematics, 1993 Let \(S^*\) be the usual class of starlike functions, i.e. \(f(z)\) of the form \(z+a_ 2 z^ 2\dots\) which are analytic and univalent in the unit disc \(U\) and which map \(U\) onto a domain starshaped with respect to the origin.

ON NORMALIZED RABOTNOV FUNCTION ASSOCIATED WITH CERTAIN SUBCLASSES OF ANALYTIC FUNCTIONS
Проблемы анализа, 2023 In this paper, we investigate some sufficient conditions for the normalized Rabotnov function to be in certain subclasses of analytic and univalent functions. The usefulness of the results is depicted by some corollaries and examples.

Radius Constants of Sigmoid Starlike Functions
, 2022 In the present investigation, we study the class of Sigmoid starlike functions, given by $\mathcal{S}^*_{SG}=\{f\in\mathcal{A}: {zf'(z)}/{f(z)}\prec 2/(1+e^{-z})\}$ in context of estimating the sharp radius constants associated with several known ...

The radius of convexity of certain analytic functions II
International Journal of Mathematics and Mathematical Sciences, 1980 In [2], MacGregor found the radius of convexity of the functions f(z)=z+a2z2+a3z3+…, analytic and univalent such that |f′(z)−1|

Support points of families of starlike mappings
, 1990 The support points are obtained for the class of those analytic functions starlike of order α, m-fold symmetric that are real on (− 1, 1). We also determine the set of support points for the m-fold symmetric analytic functions which are starlike of order

Criterion for the family of ε starlike mappings
, 2002 We introduce the family of ε starlike mappings, in purpose to treat the family of convex mappings and the family of starlike mappings as one family, and to describe one family how to transit to another one.

Inequalities of a Class of Analytic Functions Involving Multiplicative Derivative
MathematicsUsing the concepts of multiplicative calculus and subordination of analytic functions, we define a new class of starlike bi-univalent functions based on a symmetric operator, which involved the three parameter Mittag-Leffler function.

Null, recursively starlike-equivalent decompositions shrink
, 2019 A subset $E$ of a metric space $X$ is said to be starlike-equivalent if it has a neighbourhood which is mapped homeomorphically into $\mathbb{R}^n$ for some $n$, sending $E$ to a starlike set.
