Injective and Surjective Conditions
Let $T:V\to W$, where $V$ and $W$ are both vector spaces and $V$ is finite dimensional. Then $T$ is injective if and only if the nullity of $T$ is $0$, and $T$ is surjective if and only if the rank of $T$ is the dimensional of $W$.Concepts
If the dimension of $W$ is infinite, then the rank of $T$ equalling the rank of $W$ does not necessarly imply that $T$ is subjective.If
