A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Let $ V$ be a $ n$-dimensional vector space with basis $ b_1,\,\ldots , b_n$, and $ \varphi$ and $ \psi$ are the maps defined by

$\displaystyle \begin{array}{rllcll}
\varphi: V\longrightarrow V, \ & b_1\longma...
...psto b_3, & \ldots , &
b_{n-1}\longmapsto b_n, & b_n\longmapsto 0 \end{array}. $

a)
Find the matrix representation $ A$ of $ \varphi$ with respect to the basis $ b_1,\,\ldots , b_n$.
b)
Find the matrix representation $ B$ of $ \psi$ with respect to the basis $ b_1,\,\ldots , b_n$.
c)
Determine $ {\mathrm{Rg}}\, B^{\mathit k}$, for all $ k\in\mathbb{N}$.
