On the Necessary and Sufficient Condition for a Set of Matrices to Commute and Some Further Linked Results

This paper investigates the necessary and sufficient condition for a set of (real or complex) matrices to commute. It is proved that the commutator [A,B]=0 for two matrices A and B if and only if a vector v(B) defined uniquely from the matrix B is in the null space of a well-structured matrix defin...
