The paper drew up one class special spread ρ level α - convex functions and ρ level θ - spiral functions.
构造出一种推广了的ρ级α－凸函数及ρ阶θ－螺形函数，讨论并证明了其从属函数关系。
This paper using complex analyis and functional analysis,studies spirallike mappings on unit ball in several complex variables,and obtains the growth and covering theorems about a kind of spirallike mappings with zero of higher order.
以复分析与泛函分析为工具,研究多复变数单位球上的螺形映照,给出了一类螺形映照的高阶零点形式的增长和掩盖定理。
Geometry quality for these mappings can be obtained from these inqualities, and some sufficiency conditions for starlike mappings and spirallike mappings are given.
由此导出全纯映照本身的一些几何性质,并得到星形映照和螺形映照的充分判别条件。
