摘要: |
本文研究了推广的Roper-Sufiridge算子保持一些双全纯映照子族的性质.利用一些双全纯映照子族的定义,得到了推广后的Roper-Sufiridge算子在复Banach空间单位球上保持ρ次抛物形β型螺形映照及强α次殆星形映照的性质,由此得到复Hilbert空间上推广的Roper-Sufiridge算子的相应性质,推广了已有的结论. |

Abstract: |
In this paper, the authors prove that the extended Roper-Sufiridge operators preserve the properties of some subclasses of biholomorphic mappings. By the definitions of some subclasses of biholomorphic mappings, we prove that the extended Roper-Sufiridge operators preserve the properties of parabolic and spiralike mappings of type β and order ρ, strongly and almost starlike mappings of order fi on the unit ball in complex Banach spaces, and thus we obtain the corresponding properties of the extended Roper-Sufiridge operators in complex Hilbert spaces, which extend the known results. |
