Hilbert空间中框架序列扰动的新结果

摘要

研究了框架序列的扰动问题，在已有关于框架序列扰动结论的基础之上，用算子的方法来描述框架序列和另一序列之间的“接近”关系，从而得到一些框架序列扰动的新结果。最后，用例子说明本文给出的方法应用更为广泛。%This paper mainly discusses the frame sequences perturbation .On the basis of known frame se‐quences perturbation results ,connect with the operator theory ,describe the frame sequence is close to other sequence ,consequently ,we get some new results of frame sequences perturbation .At last ,an examples is given to show our improvement .
