Weighted Moore-Penrose inverses on rings
Xiangzhi Kong · Journal of Shandong University · 2011
Assuming that M,N are arbitrary matrices on rings,the necessary and sufficient conditions of the weighted Moore-Penrose inverses with respect to M,N for existences are discussed.In addition,the all solutions of A{1,3M},A{1,4N},A{1,2,3M},A{1,3M,4N} and A{1,2,3M,4N}are found.
