对α次的殆β型螺形映射,α次的β型螺形映射和α/次的强β型螺形映射,给出了定义,并且在复Banach空间中的单位球上分别得到它们的增长掩盖定理.
This paper gives the definitions of almost spirallike mappings of type α and order β, spirallike mappings of type β and order α and strongly spirallike mappings of type β and order α, and obtains their growth and covering theorems on the unit ball in complex Banach spaces respectively.
