该文从Loewner链的角度出发, 在任意有限维复Banach空间中的单位球B 上给出α 次的殆β 型螺形映射的解析特征, 进而说明推广的Roper-Suffridge算子在一类有界凸圆型域上能嵌入Loewner链.
In this paper, the authors give the characterization of almost spirallike mappings of type β and order α on the unit ball B in finite dimensional complex Banach space from the Loewner chains point of view, and prove that the generalized Roper-Suffridge extension operator can be embedded in a Loewner chain on a bounded convex circular domain.
