主要研究Hilbert空间具有闭值域的稠定闭线性算子的Moore—Penrose正交广义逆的扰动,并且在原有的第一类,第二类扰动的基础上定义了第三类和第四类扰动,并得到了相应的性质和结论.
This paper studies Hilbert space has a closed range of densely defined closed linear operator Moore-'Penorse orthogonal generalized inverse of the perturbation,and in this paper, the first class, second class of perturbations on the basis of the definition perturbation in the third and fourth categories, and the nature and conclusions.
