摘要

摘要: 现有关于矩阵方程AX-XB=C的显式解的几乎所有结论都是在A与B无公共特征值的条件下获得的。本文利用特征投影给出了方程在A与B均对称或反对称时一般解的显式形式。我们所得到的结果不仅适用于任何特征值重数情形,而且可以用来讨论该方程的一般情形。

Abstract: Almost all of the existing results on the explicit solutions of the matrix equation AX-XB=C are obtained under the condition that A and B have no eigenvalues incommon For both symmetric or skewsymmetric matrices A and B.we shall give outthe explicit general solutions of this equation by using the notions of eigenprojections The results we obtained are applicable not only to any cases of eigenvalues regardlessof their multiplicities but also to the discussion of the general case of this equation.
