Thanks! I was only concerned about the finite dimensional case anyway, I just forgot to mention it.

@joriki: Equality. I haven't heard the term internal direct sum before, but based on the definition on Wikipedia, I think that's what I'm referring to, since $\ker(f)$ and $\operatorname{im}(f)$ are subspaces of $V$.
