单位球上α次准凸映射精细的偏差定理

Sharp Distortion Theorems for Quasi-Convex Mapping of Order α on the Unit Ball

利用欧氏空间单位球的边界型Schwarz引理给出α次准凸映射在极值点处精细的行列式型偏差定理和矩阵型偏差定理.

In this article,we obtained the sharp distortion theorems of determinant and sharp distortion theorems of matrix at the extreme points for quasi-convex mapping of orderα using the Schwarz lemma at the boundary of unit ball in Euclidean space.
