摘要
本文研究了复向量空间Cn中开单位球Bn,复Banach空间中单位球B和域?p1,···,pn上一类α次殆β型螺形映照的偏差估计问题.利用不等式、矩阵及α次殆β型螺形映照的增长定理等方法,获得了上述域上的一类α次殆β型螺形映照的偏差上界估计,所得结果推广了一些已知的结论.
This paper studies the distortion estimation of almost spirallike mapping of typeβ and order α on unit ball Bnin complex vector space Cn, unit ball B on complex Banach space and Reinhard domain Ωp1,···,pn. By using the methods of inequalities, matrices and the growth and cover theorem of almost spirallike mapping of type β and order α, we obtain the distortion upper bound on the above domains, which generalizes some known conclusions.
