§1.引言 Hermite矩阵的特征值反问题是Downing和Householder在[2]中提出的,其形式如下: 问题A. 给定Hermite矩阵A,k个非零实数λ_1…,λ_k,以及满足r_+r_1+…+r_k=n的k+1个非负整数r_1,r_1,…,r_k,求一实对角矩阵D=diag(d_1,…,d_n),使得A+D的特征值为0,λ_1,…,λ_k,并且相应的重数为 r_0,r_1,…,r_k.
In this paper, the unsolvability of inverse eigenvalue problems for the hermitian matrixalmost everywhere is discussed. The method used in [6] and [7] is applied here, and somesimilar results are obtained.
