https://doi.org/10.1007/978-94-009-6848-6 as we are not usually able to prove that weak solutions actually belong to such spaces. Therefore other kind of spaces are needed: we must weaken the requirement of smoothness for the functions belonging to them. On the other hand, the bilinear form determined in (.) contains derivatives. Summing u
