Problem 3. Recall that a linear map f : V → W is called an isomorphism if it is invertible (i.e. has a linear inverse map). We proved in class that f is in fact invertible if and only if it is bijective. Use this fact from class together with the Rank-Nullity Theorem (of the previous problem) to show that if f : V → V is an endomorphism, then it is actually invertible if 1. it is merely injective...

Let (V, |· |v ) and (W, |· |w ) be normed vector spaces. Let T : V → W be linear map. The kernel of T, denoted ker(T), is defined to be the set ker(T) = {v ∈ V : T(v) = 0}. Then ker(T) is a linear subspace of V . Let W be a closed subspace of V with W not equal to V . Prove that W is nowhere dense in V .
