摘要:

定义了螺形函数的新子族, 即ρ次椭圆星形函数和ρ次椭圆形β型螺形函数,并将这些定义推广到多复变数空间中, 得到推广的Roper-Suffridge算子在不同空间不同区域上保持ρ次椭圆星形映照和ρ次椭圆形β型螺形映照的性质, 由此可以在多复变数空间中构造出许多ρ次椭圆形β型螺形映照. 所得结论丰富了对螺形映照子族及推广的Roper-Suffridge算子的研究.

关键词: Roper-Suffridge算子, 星形映照, 螺形映照, Reinhardt域

Abstract:

In this paper, we introduce some new subclasses of spirallike functions, namely elliptical starlike functions of order ρ, elliptical and spirallike functions of type β and order ρ. We extend the new definitions and obtain that the generalized Roper-Suffridge operators preserve the properties of the mappings defined in this paper on different domains in different spaces, thus many elliptical and spirallike mappings of type β and order ρ can be constructed in several complex variables. The conclusions enrich the research of subclasses of spirallike mappings and generalized Roper-Suffridge operators.

Key words: Roper-Suffridge operators, Starlike mappings, Spirallike mappings, Reinhardt domains
