论文摘要
对于内部函数，我们讨论了众所周知的压缩偏移的双重操作员。我们建立了两个双重压缩偏移的条件是单位等效的/相似的，我们描述了双重的子空间结构。
For an inner function u we discuss the dual operator for the well-known compressed shift. We establish conditions for two dual compressed shifts to be unitarily equivalent/similar and we describe the invariant subspace structure for the dual.
