从B~α到B~0和D空间上的复合算子(英文)
Composition Operators from Spaces B~α to B~0 and D
【摘要】 设φ是单位圆盘D到自身的解析映射,X是D上解析函数构成的Banach空间,对f∈X,定义复合算子Cφ:Cφf=fφ.研究了Bα到B0和D空间上的复合算子的有界性和紧性.
【Abstract】 When φ is an analytic map of the unit disk D into itself,and X is a Banach space of analytic functions on D,define the composition operator C_φ by C_φ f=fφ,for f∈X.In this paper,the boundedness and compactness of the composition operators from the spaces B~α to B~0 and D are discussed.
