You should probably go to class...

comment Wave equation on a finite domain with no internal resonance
@Pavel I am trying to use this example as a generic example. The other systems (in higher dimensions) I have in mind do not exhibit in general this internal resonance which is such that, for the above example, what we can show is fairly limited (I cannot explain all the details here, it would be too long). If this is impossible to get rid of the internal resonance for this 1D PDE, I need to investigate 2D/3D equations instead, that are much more challenging.

comment Wave equation on a finite domain with no internal resonance
@vnd Correct but I would like a set-up where the stationary solutions do not satisfy any internal resonance condition (all eigenvalues should incommensurate).

comment Weak formulation with Dirichlet boundary conditions
What would be the well-defined form of the weak formulation then? Isn't the proposed weak formulation the usual one for Poisson's equation?

@Evgeny I would suggest that your turn your comment into an answer.
