On the Coefficients Problem of quasi-convex mappings and Starlike Mapppings in C^n
收藏 引用
Chinese Quarterly Journal of Mathematics 2003年 第4期18卷 419-424页
作者: 刘维先 王予民 MathsTeachingandResearchSection HenanPoly-technicalInstitutesNanyang473009China
Let B^n be the unit ball in C^n, we study quasi-convex mappings and starlike mappings on B^n. The upper bounds of second order item coefficients ofr quasi-convex mappings and starlike mappings are obtained.
