What is the English term for "beschränkt Menge"? I tried translating the word "beschränkt" and then google, for example, "limited set", but got no results.

"beschränkt" can in this context be translated as "bounded" ("Schranke" = "bound")
General hints for the translation:

*Consider using leo.org which indicates mathematical terms with [math]. 

*Another method for translating mathematical terms is searching for it in the german wikipedia and then going to the english version of the same article. Usually on the bottom left there is a whole list of languages.
