We prove in this paper the sharp version of a starlikeness condition. The basic tool in our study is the convolution theory. We present a short history of the problem before the proof of the main result. Mathematics Subject Classification (2010): 30C45, 30A10. Keywords: Starlikeness, convexity, analytic functions, Alexander operator, Herglotz representation formula. |
