摘要：
In this paper we consider another proof of the Ozaki's condition for multivalent functions that if f (z) is analytic in a convex domain D and for some real value alpha we have Re{e(i alpha)f((p))(z)} > 0 in D, then f (z) is at most p-valent in D. Ozaki's condition is a generalization of the well-known Noshiro-Warschawski univalence condition. (c) 2023 Published by Elsevier Inc.
