Nov 4, 2007 space V . Now applying the rank-nullity theorem in the lectures to ϕ, we get dim( ker(S ◦ T)) = nullity(ϕ) + rank(ϕ) = dim(ker(ϕ)) + dim(im(ϕ)).

[Linear algebra] Can somone explain why: dim(V) = dim(Ker(T)) + dim(Im(T)) with logic and not proofs?

This subcase is analagous with Case(ii) of the 2x2 case, since Av = λv for all vectors v ∈ R3, which means A = λI, and A is already in Jordan Normal Form. In this case, the minimal polynomial is m A(t) = (t−λ). Subcase(b) dim(ker(A−λI)) = 2.
