关于两个Hilbert空间中的双曲理论的几个结果
A few results on Mourre theory in a two-Hilbert spaces setting
摘要:
我们介绍了一个自然的框架,在一个抽象的两个希尔伯特空间设置处理的理论。特别地,从作用在辅助Hilbert空间中的一对自伴算子(H_0,A_0)的类似估计,导出了一对自伴算子(H,A)的近似估计.给出了两个Hilbert空间中波算子完备性的一个新判据。
英文摘要:
We introduce a natural framework for dealing with Mourre theory in an abstract two-Hilbert spaces setting. In particular a Mourre estimate for a pair of self-adjoint operators (H,A) is deduced from a similar estimate for a pair of self-adjoint operators (H_0,A_0) acting in an auxiliary Hilbert space. A new criterion for the completeness of the wave operators in a two-Hilbert spaces setting is also presented.
