Given a subdomain of GL(n), when is the map from matrices to their matrices of eigenvectors ...

Whatever the way you define your map, you cannot expect a diffeomorphism for dimension reasons. The simple fact that you can rescale your eigenvectors makes you lose some dimensions (at least n). In a …
