A note on Ozaki's condition
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 α we have Re{eiαf(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 N...

Summary: | 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 α we have Re{eiαf(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. |
