内函数的Taylor系数与移位的Beurling定理

Taylor coefficients of inner functions and Beurling's theorem for the shift

Dragan Vukotić

摘要:

本文的目的是证明一个舒尔型定理,该定理用泰勒系数来刻画内函数。根据Beurling定理,这提供了$\ell^2$的移位不变子空间的序列特征。

英文摘要:

The purpose of this expository note is to give a proof of a Schur-type theorem that characterizes the inner functions in terms of their Taylor coefficients. In view of Beurling's theorem, this provides a sequential characterization of the shift-invariant subspaces of $\ell^2$.
