Aug 25, 2017 at 21:33 comment added Zinkin @LSpice I am sorry for making that impression, I just wanted to be sure that it is really a rather implicit concept since this is the main point why I asked here. You see, I suppose if you are not working in the field of nonlinear PDEs you may ask yourself at some point: Is this a concept that I should be interested in (because compactness is of course one of the strongest tools at hand) and apparently the answer to this one is "almost certainly this concept will not be too relevant".
Aug 25, 2017 at 19:53 comment added LSpice It seems that the answer to your question literally as written ("Is there a comprehensive theorem …") is just "no", but that is not a very useful answer; and yet you seem to be responding to attempts to give a more useful answer by objecting that they aren't comprehensive theorems. (It's not other people's responsibility to do the work of reading books and extracting statements of sufficient generality to satisfy you!)

Aug 25, 2017 at 10:49 comment added Zinkin I am looking for a single theorem and you recommend me an entire book ;) ...
