Them (King Diamond album)
Through the blood they commutate or take control of those who drink it. Grandma cuts King's sleeping mother's hand and adds her blood to the teapot.

Commutativity in rings of matrices Let n be arbitrary positive integer and R arbitrary ring (perhaps, non-associative). Let's denote $M_n(R)$ the set of all $n х n$ matrices with entries from R. As i know if R is non...
$M$ is in the center of $M_n(R)$ iff $M$ commutes with all matrices $E_{ij}$ (the $(i,j)$th entry equals $1$ and others $0$). From here you can easy obtain the answer.

It has been proposed to switch the inverter stage into a free-wheeling state, and then to commutate the rectifier stage with zero dc-link current.

On diagonizability of commutating matrices Let $A$ and $B$ be $n\times n$ matrices over the Galois Field of order $p$ ($p$ is a prime). Suppose that $A$ and $B$ are diagonizable matrices and that they commutate. Is it...
Yes, this will work fine, as long as we assume that $A$ and $B$ have all their eigenvalues in $GF(p)$ (or, equivalently, strengthen your assumption to say that $A$ and $B$ are diagonalizable over $GF(p)$. Possibly this is already what you intended.) The proof which you cite works over any field; the...

Do matrices commutate under self multiplication? Suppose we have any matrix $A$, then $A^n = A.A^{n-1} = A^{n-1}.A$ Will this hold for any matrix $A$ or do we have to have some restrictions on matrix $A$? More gener...
In order to be able to find $A^2$ we need $A$ to be a square matrix that is $n\times n $ matrix. If the matrix is a square matrix, then the multiplication of powers of $A$ is commutative and $$A^{n+m} = A^n.A^m = A^m.A^n$$

Matrix Commutativity **Question 1** If I have a 3 by 3 skew symmetric matrix, K(t) (K(t) and K'(t) doesn't commute) what would it be $\frac{\mathrm{d}(K(t)^n) }{\mathrm{d} t} \tag 1$? is it $(n) K(t)^{n-1}K'(t) \ta...
When multiplication is non-commutative, you have to apply the product rule for derivatives more carefully: $$\frac{d}{dt}(K(t)^2) = \frac{d}{dt}(K(t) \cdot K(t)) = K'(t) \cdot K(t) + K(t) \cdot K'(t)$$ Notice the different ordering of the 2 terms on the right side. This is _not_ equal to $2 K(t) K'(...
