Commutators from a hyperplane of matrices
Denote by $M_n(K)$ the algebra of $n$ by $n$ matrices with entries in the field $K$. A theorem of Albert and Muckenhoupt states that every trace zero matrix of $M_n(K)$ can be expressed as $AB-BA$ for some pair $(A,B)$ of matrices of $M_n(K)$.

The weighted Moore-Penrose inverse for sum of matrices
In this paper we exhibit that under the rank additivity condition r(A+ B) = r(A)+ r(B) , a neat relationship between the weighted Moore-Penrose inverse of A+B and the weighted Moore-Penrose inverses of A and B . Mathematics subject classification (2010):

Reverse order law for weighted Moore-Penrose inverses of multiple matrix products
In this paper by using some matrix rank theories, we derive equivalent conditions for reverse order law of weighted Moore-Penrose inverses of multiple matrix products.

Weak MPCEP and *CEPMP inverses
We generalize the systems of equations, which introduced the MPCEP and *CEPMP inverses, using a minimal rank weak Drazin inverse and a minimal rank right weak Drazin inverse.
