Given a set of matrices

$M = \left\{\begin{bmatrix}1&a\\0&3\end{bmatrix} \mid a \in \mathbb R\right\},$

what does the notation $A_a^n, n \in \mathbb N$ mean?

    Addendum: `bmatrix` gives bracketed matrices, which is what you seem to want.2011-04-19

$A_a$ seems to be a shorthand for a typical matrix in $M$. Then $A_a^n$ is the $n$-th power of $A_a$.

    Yes, it appears that's what it means. Thanks!2011-04-19
