+Before proving this theorem, we embark upon a long string of definitions.
 For expository purposes, we begin with the $n=1$ special cases, and define
 first topological $A_\infty$-algebras, then topological $A_\infty$-categories, and then topological $A_\infty$-modules over these. We then turn
 to the general $n$ case, defining topological $A_\infty$-$n$-categories and their modules.
