- functional analysis - Where can I find the paper Un théorème de . . .
J P Aubin, Un théorème de compacité, C R Acad Sc Paris, 256 (1963), pp 5042–5044 It seems this paper is the origin of the "famous" Aubin–Lions lemma This lemma is proved, for example, here and here, but I'd like to read the original work of Aubin However, all I got is only a brief review (from MathSciNet)
- study of the sequence (Un) defined by $U_ {0}=a$ and $U_ {n+1}=a+\frac . . .
Show that (Un) is bounded, convergent and find its limit To prove that the sequence is bounded i intuitively used the fixed point theorem because at first glance i don't really know the appropriate way to study this sequence as it's neither arithmetic nor geometric or the both

- Can you describe all the ways to un-localize a ring?
You might consider the word "globalize" rather than "un-localize" This term is used in number theory and algebraic geometry, for instance in Ravi Vakil's or Eisenbud-Harris's books
