Webb3 juli 2024 · An injective linear map between two finite dimensional vector spaces of the same dimension is surjective. General topology An injective continuous map between … Webbby hand. However, for linear transformations of vector spaces, there are enough extra constraints to make determining these properties straightforward. Our rst main result along these lines is the following. Theorem. A linear transformation is injective if and only if its kernel is the trivial subspace f0g. Proof. Suppose that T is injective.
