PERTURBATION UPPER BOUNDS OF EIGENVALUE OF HERMITE MATRIX AND SYMMETRIZABLE MATRIX

Zhang Qimei;Zhang Lan;Faculty of Science, Inner Mongolia University of Technology;  
In this paper, by using the unitary decomposition of Hermite matrix and singular value decomposition of general matrix, we obtain the upper bounds of the absolute perturbation of eigenvalues of Hermite matrix and symmetrizable matrix, improve the previous results and generalize theorems of Kahan and WielandtHoffman.
