两矩阵乘积的{1,3M,4N}-逆的反序

On Reverse Order Law for {1 ,3M ,4N}-inverse of Two Matrix Product

利用广义Schur补的极大秩研究了两个矩阵乘积的{1,3M,4N}-逆的反序,给出了反序B{1,3N,4K}A{1,3M,4N}■(AB){1,3M,4K}成立的充分必要条件.

In this paper, we study the reverse order law for {1,3M,4N}-inverse of two matrix product by using the maximal rank of generalized Schur complement. We derive the equivalent condition for B{1,3N,4K}A{1,3M,4N} lohtain in （AB）{1,3M,4K} .
