Perhaps you should try some spelling variations:
order mathematical » other mathematical, modern mathematical, cover mathematical
der mathematical » her mathematical, mer mathematical, over mathematical
other surveys » other survey, other surgeons
oder surveys » der surveys, cover surveys, user surveys
und ihrer » und ihr

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ergebnisse ((der mathematical) OR (order mathematical)) ((und ihrer) OR (und ihre)) grenzgebiete. 2. folge, a series of ((oder surveys) OR (other surveys)) in mathematics.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ergebnisse ((der mathematical) OR (order mathematical)) ((und ihrer) or (und ihre)) grenzgebiete. 2. folge, a series of ((oder surveys) or (other surveys)) in mathematics".
• Adding a wildcard symbol may retrieve word variants: ergebnisse ((der mathematical) OR (order mathematical)) ((und ihrer) or (und ihre)) grenzgebiete. 2. folge, a series of ((oder surveys) or (other surveys)) in mathematics*.
