The generalized inverse has numerous important applications in aspects of the theoretic research matrices and statistics. One core problems is finding necessary sufficient conditions for reverse (or forward) order laws matrix products. In this paper, by using extremal ranks Schur complement, some are given forward law A1{1,2}A2{1,2}…An{1,2}⊆(A1A2…An){1,2}.
