comment $\mathcal{D}(0,T;V)$ is dense in $W(0,T)$
@AndrasBatkai thank you a lot. Unfortunately I don't have access to that. Do you have a PDF of that (if legal, otherwise obviously ignore this)?

$[0,T]$ is an interval. This is a research-level question.

But how do we know that the solution satisfies the BC without assuming the solution is smooth enough?
