I am talking about this one. Maybe I am being stupid, but I don't see anything wrong with it. Could those who closed it please explain what I am missing? Or was it just a case of people not having heard the word "nuclear space" and being trigger happy in assuming that if they haven't heard of it, then it doesn't exist?
Edit: I just saw that the same user is posting questions about radius of convergence of complex power series and, at the same time, about automorphic representations. Now, I am puzzled.
