| Abstract: |
| This paper studies the distortion estimation of almost spirallike mapping of type β and order α on unit ball Bn in 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. |
