Volume 35 • Number 2 • 2012   • The Radius of Convexity and a Sufficient Condition for Starlike Mappings Ming-Sheng Liu and Yu-Can Zhu Abstract. An estimate is provided for the radius of convexity of starlike mappings in the Euclidean unit ball $B^n$, and a sufficient condition is obtained for starlike mappings, which give the $n$-dimensional versions of the corresponding results of one complex variable. 2010 Mathematics Subject Classification: 32H05, 30C45.
