论文摘要
我们解决了$（a+b）^{\ dagger} = a^{\ dagger}+b^{\ dagger}的问题，其中$ \ dagger $表示摩尔 - 荷兰倒数。该组的逆问题也是一个类似的问题。
We address the question as to when it is true that $(A+B)^{\dagger}=A^{\dagger}+B^{\dagger},$ where $\dagger$ denotes the Moore-Penrose inverse. A similar question is addressed for the group inverse.
