主要讨论整环上矩阵的一类加权Moore—Penrose逆。给出了整环上矩阵的一类加权Moore—Penrose逆的子式表达式,并给出这类加权Moore—Penrose逆存在的充要条件。
The generalized Moore-Penrose inverse is investigated over integral domains. New determinantal representations of the weighted Moore-Penrose inverse are introduced, and necessary and sufficient conditions for its existence over an integral domain are obtained.
