A family of 512 reverse order laws for generalized inverses of a matrix product: A review
Reverse order laws for generalized inverses of matrix products are a classic object of study in the theory of generalized inverses. One of the well-known reverse order laws for a matrix product AB is (AB)(i,…,j)=B(s2,…,t2)A(s1,…,t1), where (⋅)(i,…,j ...

Reverse-order law for the Moore–Penrose inverses of tensors [PDF]
Reverse order law for the Moore-Penrose inverses of tensors are useful in the field of multilinear algebra. In this paper, we first prove some more identities involving the Moore-Penrose inverse of tensors. We then obtain a few necessary and sufficient conditions for the reverse order law for the Moore-Penrose inverse of tensors via the Einstein ...

Further Results on the Reverse Order Law for {1,3}-Inverse and {1,4}-Inverse of a Matrix Product
Both Djordjević (2007) and Takane et al. (2007) have studied the equivalent conditions for B{1,3}A{1,3}⊆(AB){1,3} and B{1,4}A{1,4}⊆(AB){1,4}.
