Perhaps you should try some spelling variations:
"mathematics models in physics" » "mathematic model in physics", "mathematics modeling in physics", "mathematics more in physics"
"mathematical models in physics" » "mathematical modelings in physics", "mathematical methodss in physics"
"mathematical model in physics" » "mathematical modeling in physics", "mathematical methods in physics"

Try widening your search to All Fields.

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: (("mathematical models in physics") OR ((("mathematics models in physics") OR ("mathematical model in physics")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mathematical models in physics\") or (((\"mathematics models in physics\") OR (\"mathematical model in physics\"))))".
• Removing quotes may allow a broader search: (( mathematical models in physics ) or ((( mathematics models in physics ) OR ( mathematical model in physics )))).
• Adding a wildcard symbol may retrieve word variants: (("mathematical models in physics") or ((("mathematics models in physics") OR ("mathematical model in physics"))))*.
