Suppose v1,…,vm is a list of vectors in V. Define T∈L(Fn,V) by
T(z1,…,zm)=z1v1+⋯+zmvm
- What property of T corresponds to v1,…,vm spanning V?
- What property of T corresponds to v1,…,vm being linearly independent?
Note range T denotes the span of v1,…,vm and null T denotes all linear combinations giving zero
- T being surjective, or equivalently range T=V
- T being injective, or corresponds null T={0} (no combinations give zero)
