一类单边算子权移位的谱

The Spectrum of a Class of Unilateral Operator Weighted Shifts

本文首先给出重数有限的单边算子权移位的等价表示,进而对一类具有下(上)三角权的移位给出简单方便的计算谱的方式.

In this short note,we show an equivalent representation of unila- teral operator weighted shifts with finite multiplicity.As a result,we give a simple computational method for spectrum of a class of unilateral operator weighted shifts with lower (upper) triangular weights.
