Hi there! :) I'm trying to understand a theorem, but it's full with analysis (or something) terms unfamiliar to me. Is there an intuitive interpretation for the sentence: 'An operator being limited is equivalent to continuity in the topolgy of the norm'? Also, how can I partially understand what is a "strongly continous application"? I understand that for a plain comprehension, one is required to follow a strict study on these subjects. But right now I'm happy with a simple intuition. Edit: Is this the right place? I'm not sure analysis is the subject here!
