给定复平面中单位圆盘D上的全纯自映射妒,设u∈H(D),定义H(D)上的加权微分复合算子Dnu为(Dφnuf)(z)=u(z)·f(n)φ(z)),/∈H(D),z∈D.利用泛函分析和复分析的方法,讨论了Bers型空间(或小Bers型空间)之间加权微分复合算子Dnu的有界性和紧性,得到了若干充要条件
Given φ a holomorphic self-map on unit disc D of complex plane, let u ∈ H(D). The weighted differentiation composition operator D~,u onH(D)is defined as D(φ,uf z)=u(z).fn((,φ(z)), f∈H(D), z∈ D. By using the method of functional analysis and complex analysis, the boundedness and compactness of the operator Dg,u is discussed between Bers-type spaces as well as little Bers-type spaces, and some sufficient and necessary conditions are obtained.
