Since panels are installed even in Northern Europe nowadays, this specification is essential to get a complete picture.

It is not true that any linear operator on a function space (which should anyway then be defined, in particular regarding differentiability of the functions in that space) is implemented by a differential equation or differential operator. A trivial counter example it the evaluation of a function in one point. Tags: nowiki added Visual edit
