摘要
利用增长定理,得到了α次的殆β型螺形映射f沿着单位多圆柱上某个单位方向上的偏差定理.又进一步估计了α次的殆β型螺形映射f在Banach空间单位球上某个单位方向上偏差的上界.
We will establish distortion theorems of Jacobian matrix for almost spirallike mappings of type β with order α along a unit direction on the unit polydisc.We also obtain the upper bound estimate of a distortion theorem for almost spirallike mappings of type β with order α on the unit ball of a complex Banach space
