The Range and Null Space of the Zero Transformation of Vector Spaces
Problem 555
Let $U$ and $V$ be vector spaces over a scalar field $\F$.
Define the map $T:U\to V$ by $T(\mathbf{u})=\mathbf{0}_V$ for each vector $\mathbf{u}\in U$.
(a) Prove that $T:U\to V$ is a linear transformation.
(Hence, $T$ is called the zero transformation.)
(b) Determine the null space $\calN(T)$ and the range $\calR(T)$ of $T$.
