Liu, Yong Hui et Wei, Mu Sheng, On the Block Independence in G.Inverse and Reflexive Inner Inverse of A Partitioned Matrix, Acta mathematica Sinica. English series (Print) , 23(4), 2007, pp. 723-730
By applying the multiple quotient singular value decomposition QQQQQ.SVD, we study the block independence in g.inverse and reflexive inner inverse of 2.2 partitioned matrices, and prove a conjecture in [YijuWang, SIAM J. Matrix Anal. Appl., 19(2), 407.415(1998)].
