ε星形映照族(Ⅱ)

在文[1]中定义了e星形映照族,给出了其在复Banach空间及Cn中的域上的判别准则,讨论了Roper-Suffridge算子.本文将进一步讨论Roper-Suffridge算子,并给出单位圆上ε星形映照族的增长定理的上界估计.     

多圆柱上的完全准凸映射

在C~n中有界凸Reinhardt域上讨论了一类介于凸映射类与星形映射类之间的“完全准凸映射类”.特别地,在C~n中的多圆柱上给出了完全准凸映射的分解定理,得到了多圆柱上判别凸映射的一个改进的充分条件.

THE GENERALIZED ROPER-SUFFRIDGE EXTENSION OPERATOR

This note induces some generalized Roper-Suffridge extension operators such that they are used to construct some almost starlike mappings of order α and starlike mappings of order a on different domains.     

高师院校复变函数课程教学改革的探索

结合多年的教学实践和高师院校的特点,分析了复变函数课程教学中存在的问题,并提出了一些教学改革设想,如改革课程内容,进行教材建设,渗透数学文化,加强网络教学等,期望能为该课程的教学改革抛砖引玉.     

有界对称域上的加权Bergman空间

On bounded symmetric domain Ω of Cn.we investigate the properties of functions in weighted Bergman spaces Ap(Ω,dvs)for 0＜P≤ ∞and-1＜s＜ ∞.Based on the estimate of Bergman kernel,we obtain some characterizations of functions in Ap(Ω,dvs)in terms of a class of linear operators Dα,β.Making use of these characterizations,we extend Ap(Ω,dvs)to the weighted Bexgman spaces APα,β(Ω,dvs)in a very natural way for 1≤p≤ ∞ and any real number s,that is,-∞＜s＜ ∞.This unified treatment covers some classical Bergman spaces,Besov spaces and Bloch spaces.Meanwhile,the boundedness of Bergman projection operators on Apα,β(Ω,dvs)and the dual of Apα,β,(Ω,dvs)are given.     

关于全纯映照模的Schwarz引理一点注记

记DC为单位圆盘,B~k C~k为开欧氏单位球,Ω是C~k(或C)中的域.记H_n(D,Ω)为满足一定条件的全纯映照族(或函数族)的全体.作者证明了若,∈Hn(D,D),则|f′(z)|≤(n|z|~(n-1))/(1-|z|~(2n))(1-|f|(z|~2),z∈DD同时,对Hn(D,B~k)中映照的模也得到类似的结果.该结论推广了Pavlovic的相应结果.
