Perhaps you should try some spelling variations:
her mathematical » mer mathematical, other mathematical, over mathematical
ergebnisse her » ergebnisse h, ergebnisse haben, ergebnisse host
modern surveys » oder surveys, modern purveyors, modern surgery
modern survey » modern surgery, models survey, model survey
und ihrer » und ihre
und ihr » und ihre

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "ergebnisse her mathematical ((und ihrer) or (und ihr)) grenzgebiete. 2. folge, a series of ((modern surveys) OR (modern survey)) in mathematics".
• Adding a wildcard symbol may retrieve word variants: ergebnisse her mathematical ((und ihrer) or (und ihr)) grenzgebiete. 2. folge, a series of ((modern surveys) OR (modern survey)) in mathematics*.
