Analysis provides novel conclusions on the sum of K-frames in Hilbert space, indicating improved results and examples.
In this paper, in term with the analysis operator and bounded linear operators, we give some novel conclusions on the sum of K-frames in Hilbert space, which completely improve and generalize the existing results of the sum of K-frames, and construct some numerical examples to illustrate the validity and rationality of our conclusions.
