不同Hilbert空间之间的交织算子:与框架的联系
Intertwining operators between different Hilbert spaces: connection with frames
摘要:
本文推广了作者最近提出的一个关于缠绕算子的策略。特别是,我们讨论了扩展我们以前的结果,以这种方式来构建(几乎)等谱自伴算子生活在不同的希尔伯特空间的可能性。文中还对许多实例进行了详细讨论。它们中的许多来自希尔伯特空间中的框架理论,另一些来自所谓的g-框架。
英文摘要:
In this paper we generalize a strategy recently proposed by the author concerning intertwining operators. In particular we discuss the possibility of extending our previous results in such a way to construct (almost) isospectral self-adjoint operators living in different Hilbert spaces. Many examples are discussed in details. Many of them arise from the theory of frames in Hilbert spaces, others from the so-called g-frames.
