本文刻画了单位圆盘自同构φ产生的、源于离散测度的复合算子C_φ的所有奇异内本征函数。通过建立Beurling不变子空间与模型不变子空间之间的联系,我们对所有内函数进行分类,使得对应Beurling子空间在非椭圆自同构诱导的复合算子下不变,该分类涉及求解复合算子的本征函数方程。此外,我们还给出了上述联系的若干应用。
英文摘要
This paper characterizes all the singular inner eigenfunctions of the composition operators $C_ϕ$ that arise from discrete measures, when $ϕ$ is an automorphism of unit disk. By establishing a connection between Beurling and model invariant subspaces, we classify all the inner functions so that the corresponding Beurling subspace is invariant under the composition operators induced by non-elliptic automorphisms. This classification involves solving the eigenfunction equation for the composition operator. Further, we present some applications of the above-mentioned connection.
