摘要
利用泛函分析中的算子理论讨论了Hilbert空间中Riesz框架和框架扰动的稳定性结果.并且改进了已有的相关结果:将线性算子的条件是可逆的减弱为是满的,证明了对于Riesz基也有类似的扰动性结果.
Using the operator theory in functional analysis, discussed the stability of Riesz frames and frames under perturbation in Hilbert space. The results corresponding the previous ones are improved: the condition that the operator invertible is changed with the one that surjective, and the stability of Riesz basis under perturbation is similar.
