comment Complex exponentiation
wouldn't this just involve choosing a particular branch for the $\log(z)$?

comment Proof of “Eigenvectors corresponding to different eigenvalues are linearly independent.”
@jacob If all $c_k \equiv 0$, then $v_1 = \vec{0}$, so this cannot happen. Alternatively, if $\lambda_1 = \lambda_k \forall k$, then the eigenvectors $v_k$ turn out to correspond to the same eigenvalue.

comment Proof of “Eigenvectors corresponding to different eigenvalues are linearly independent.”
@jacob $v_k \lambda_k = A v_k$ and so $$\sum c_k v_k \lambda_k = \sum c_k A v_k = \sum A c_k v_k = A \sum c_k v_k$$ since matrix multiplication commutes with constant multiplication.
