ON ¿-COMMUTATIVE MATRICES*
Definition 3 The matrices A and B of order n are mutually k-commuta-tive, if say A is k-commutative with respect to B and if B is at most k-commuta-tive with respect to A If A and B are commutative in the usual sense, then they are mutually one-commutative The quasi-commutative matrices defined by McCoy (XV)
Joint numerical ranges and commutativity of matrices
Commutative normal matrices Polyhedral set 1 Introduction Denote by Mn the set of n x n complex matrices Let c e IR n be a real vector with entries Cl > The joint c-numerical range of A (Al, , Am) e M m is defined by is an orthonormal set a; — cn, then Wc(A) {Cl (trA1, , trAm)} We will always assume that Cl > cn to avoid this trivial If -
THE ALGEBRA GENERATED BY THREE COMMUTING MATRICES
matrices is zero These matrices hence commute, and the linear subspace of M n(C) spanned by them is closed under multiplication Adding constant multiples of the identity to this space so as to have a \1," we therefore get a commutative subalgebra of M n(C) of the maximum dimension 1+bn2=4c possible by Schur’s theorem
ON QUASI-COMMUTATIVE MATRICES*
commutative matrices * 2 Commutative matrices In this section we shall make some preliminary remarks and then mention a few known properties of commutative matrices which will be needed in later sections Let ï be a given matrix of order », with the elementary divisors (X—X¿)Pi (í = 1, 2, • • • , r)

Matrices, transposes, and inverses
Feb 01, 2012 · The notion of an inverse matrix only applies to square matrices - For rectangular matrices of full rank, there are one-sided inverses - For matrices in general, there are pseudoinverses, which are a generalization to matrix inverses Example Find the inverse of A = 11 11 Wehave 11 11 ab cd = 10 01 =⇒ a+cb
