P-标准形与Drazin逆

P-canonical forms and Drazin inverses

Mohammed Moucouf

摘要:

本文定义了$\mathcal{P}$ -$(A^{k})_{k}$(或简称为矩阵$A$)的标准形,并证明了它们的一些性质。它还表明,我们如何可以从中推导出许多有趣的信息矩阵$A$。证明了$A$的$\mathcal{P}$ -标准形可以表示为$A$的几何部分和非几何部分之和,并且证明了$A$的Drazin逆$A_{d}$的$\mathcal{P}$ -标准形可以通过将$k$的$-k$简单地插入到$A$的几何部分中来推导.最后,给出了几个算例来说明所得结果.

英文摘要:

In this paper, $\mathcal{P}$-canonical forms of $(A^{k})_{k}$ (or simply of the matrix $A$) are defined and some of their properties are proved. It is also shown how we can deduce from them many interesting informations about the matrix $A$. In addition, it is proved that the $\mathcal{P}$-canonical forms of $A$ can be written as a sum of two parts, the geometric and the non-geometric parts of $A$, and that the $\mathcal{P}$-canonical form of the Drazin inverse $A_{d}$ of $A$ can be deduced by simply plugging $-k$ for $k$ in the geometric part of $A$. Finally, several examples are provided to illustrate the obtained results.
