摘要
本文讨论矩阵的Γα-逆与星序。给出了Γα-Moore-Penrose逆存在的一些条件、Γα-Moore- Penrose逆与星序的联系以及星序的一些Γα-逆刻画。
The matrix Гα-inverses and the star ordering are discussed. Some conditions on existence of Гα-Moore-Penrose inverses are derived. The relations between the Гα-Moore-Penrose inverses and the star ordering, some characterizations on Гα- inverses of the star ordering are given.
