摘要
设复矩阵Ａ的特征值为λ１，…，λｎ．本文的目的，首先给出和的不等式用以改进Ｓｃｈｕｒ不等式，然后应用这些不等式去估计矩阵Ａ的特征值．
Let the n ×n complex matrix A have complex eigenvalues λ1, λ2,…,λn. The purpose of this paper is first to deduce aditional inequalities for and,which improve the Schur inequalities,and then use these inequalities to estimate eigenvalues of the matrix A.
