Here we provide two proofs. The first operates in the general case, using linear maps. The second proof looks at the homogeneous system for with rank and shows explicitly that there exists a set of linearly independent solutions that span the kernel of . While the theorem requires that the domain of the linear map be finite-dimensional, there is no such assumption on the codomain. This means that there are linear maps not given by matrices … WebUsing the Rank-nullity theorem, we give a short proof of the following result.
