On the Closed Range of Block Operator Matrices
主要研究分块算子矩阵值域的闭性问题.运用扰动理论和Hyers—Ulam稳定性,给出分块算子矩阵值域为闭的充分条件.最后用一些例子说明判别准则的有效性.
In this paper, the closed range of block operator matrices is studied. Using the perturbation theory and Hyers-Ulam stability, the sufficient conditions of the closed range of operator matrix are given. In the end, some examples are given to illustrate the effectiveness of the proposed criterion.
