Criteria for strongly starlike functions
Complex Variables and Elliptic Equations, 1997Let A n be the family of normalized regular functions f, where f(z)=z+an+1zn+1+…, in the unit disc Δ and let S(α) and T λ be the families of functions f such that respectively. S(α) is the class of strongly starlike functions. Further, let S ∗(α) denote the well-known family of starlike functions of order α.

On the subordination and superordination of strongly starlike functions
Mathematica Slovaca, 2016Abstract In this paper, we prove a general result that can be a sufficient condition for f to be in the some subclass of strongly starlike functions. Also, the related sandwich-type results are given.

The order of starlikeness of some classes of strongly starlike functions
Quaestiones Mathematicae, 2017In this paper we consider the order of strongly starlikeness for functions in Silverman's class Gb and in the generalized Mocanu's class M (α, β1, β2). Some previous results are improved.Mathematics Subject Classification (2010): Primary 30C45; Secondary 30C80.Keywords: Analytic, starlike, convex, strongly starlike ...

On the order of strongly starlikeness in some classes of starlike functions
Acta Mathematica Hungarica, 2014Let \(\mathcal A\) be the class of all analytic functions \(f\) in the unit disk \(\mathbb D\), of the form \(f(z)=z+\sum_{n=2}^\infty a_nz^n\) and \(\mathcal S\) the class of all univalent functions in \(\mathcal A\). Let \[ \mathcal G_b:=\{f\in\mathcal A:\left| \frac{1+zf''(z)/f'(z)}{zf'(z)/f(z)}-1\right|
