On starlikeness of $p$ -valent analytic functions

Mamoru Nunokawa$, Janusz Sokol

The known Ozaki's condition says that $Re {f^{(p)} (z)} > 0$ for $∣ z ∣ < 1$ implies that $f (z) = z^{p} + a_{p + 1} z^{p + 1} + \dots$ is at most $p$ -valent in $D$ . In…

An extension of Nunokawa lemma and its example

Hitoshi Shiraishi, Mamoru Nunokawa

For analytic functions p(z) in the open unit disk U with p(0)=1, Nunokwa has given a result which called Nunokawa lemma (Proc. Japan Acad., Ser. A 68 (1992)). By studying Nunokawa…

Ikkei Hotta, Mamoru Nunokawa

In this note we investigate the inclusion relationship between the class of strongly starlike functions of order alpha and type beta and the class of strongly convex functions of o…
