On a class of starlike functions. II

1982
[For part II see the author in J. Korean Math. Soc. 19, 29-38 (1982; Zbl 0497.30014).] Let \(S^*_ p(\alpha,\beta,\gamma)\) denote the class of functions f of the form \(f(z)=z+\sum^{\infty}_{n=1}a_{p+n} z^{p+n}\) \((p\in N=\{1,2,3,...\})\), which are analytic and starlike in the unit disk satisfying the condition \[ | \frac{A(z)-1}{2\gamma \{A(z ...

\(M\)-almost-starlike functions

1993
Let \(S\) be the usual class of normalized univalent functions in the unit disk \(\Delta\). Given \(M>1\) let \(S(M)= \{f\in S: | f(z)|< M\) for all \(z\in\Delta\}\) and let \(M(S)= \{f\in S: f(z)/M\in f(\Delta)\) for all \(z\in \Delta\}\). The author calls such functions \(M\)-almost starlike and proves that \(\varphi\in S\) is in \(M(S)\) if and only
