两个幂等算子线性组合的Drazin逆
On the Drazin Inverse of Linear Combinations Associated with Two Idempotents
利用空间分解的技巧,在条件PQP=QPQ下,得到两个幂等算子P和Q的多线性组合aP+bQ+cPQ+dQP+ePQP的Drazin逆的表达式.
We using the technique of space decompositions,the representation of the Drazin inverse for multiplicative combination aP+bQ+cPQ+dQP+ePQP associated with two idempotents P and Q is obtained under the condition PQP=QPQ.
