摘要：

The property of "reverse order law" related to generalized inverses of a matrix product AB, is the property (AB)(-) = B- A(-) for some A(-), B- and (AB)(-) generalized inverses of A, B and AB respectively. When this property holds for all generalized inverses of them, which means that it is invariant under generalized inverses, we call this "reverse order property invariance". In this paper we will investigate certain invariance properties of the product AB(-)C for studing some equivalent conditions for the reverse order property invariance. The references of Y. Tian will be the basic idea of the proofs throughout the paper.
