Perhaps you should try some spelling variations:
ihrer grenzgebiete » ihre grenzgebiete, ihren grenzgebieten, der grenzgebiete
mathematical und » mathematical union, mathematical using, mathematical user
mathematica und » mathematica _, mathematica a
modern survey » modern surgery, models survey, modeling survey
model survey » models survey, model surgery, moral survey

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