Given a linear map $\alpha: V\to W$ . The set

$\displaystyle \operatorname{Ker}(\alpha) := \{v \in V:\ \alpha(v) = 0\}$

is called kernel of $\alpha$ , and the set

$\displaystyle \operatorname{Im}(\alpha ) := \{w\in W:\ \exists v \in V\$ mit $\displaystyle \ \alpha(v)= w \}$

is called image of $\alpha$ .
