该文给出Hilbert空间中框架扰动的新结果,也讨论Riesz基,近-Riesz基和Riesz框架的扰动问题.所得结果包含一些已知扰动结果.
In this paper, some new results of frame perturbation in Hilbert spaces are obtained. The authors also discuss perturbations of Riesz bases, near-Riesz bases and Riesz frames. Moreover, it is showed that many known results are corollaries of the results.
