论文摘要
使用sz.-nagy-foias的工具,我们详细描述了操作员$ s \ oplus s^* $的不变子空间,其中$ s $是希尔伯特空间上的单方面变化。这回答了Câmara和Ross的问题。
Using the tools of Sz.-Nagy--Foias theory of contractions, we describe in detail the invariant subspaces of the operator $ S\oplus S^* $, where $ S $ is the unilateral shift on a Hilbert space. This answers a question of Câmara and Ross.
