On Nunokawa's conjecture for multivalent functions
Published online by Cambridge University Press: 17 April 2009
Abstract
The object of this paper is to prove a conjecture given recently by Nunokawa that if f(z) ∈ Α(p) satisfies Re{1 + zf″(z)/f′(z)} < p + 1/2 in the unit disk U, then f(z) is p-valently starlike in U.
