Perhaps you should try some spelling variations:
ihre grenzgebiete » ihren grenzgebieten, die grenzgebiete, im grenzgebiet
der mathematical » her mathematical, order mathematical, over mathematical
mer mathematical » her mathematical, mpr mathematical, over mathematical
oder surveys » der surveys, other surveys, cover surveys

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