This category contains results about Rings of Square Matrices.


Let $R$ be a ring.

Let $n \in \Z_{>0}$ be a (strictly) positive integer.

Let $\map {\mathcal M_R} n$ denote the $n \times n$ matrix space over $R$.


Let $+$ denote the operation of matrix entrywise addition.

Let $\times$ be (temporarily) used to denote the operation of conventional matrix multiplication.


The algebraic structure:

$\struct {\map {\mathcal M_R} n, +, \times}$

is known as the ring of square matrices of order $n$ over $R$
