   Format: MarkdownItexI corrected the definition of [[proper map]] of locales by adding the "Frobenius" condition $f_*(U\cup f^*(V)) = f_*(U) \cup V$. I also changed the note about geometric morphisms to not say that tidiness is a "generalization" of properness, since it is actually a stronger condition even for locales.
