摘要
针对一个K-Riesz框架与一个序列的和如何能构成新K-Riesz框架的问题,提出用算子理论研究的方法,得到构成新K-Riesz框架的充分条件.所得结论更正Riesz框架中的相关结论.
According to the operate theory,the paper suggest a new research method to solve the problem of how the sum of a K-Riesz frame and a sequence generating a new K-Riesz frame.Then the sufficient conditions for generating a new K-Riesz frame are obtained.The results in the paper correct the remarkable results of Riesz-frames.
