Perhaps you should try some spelling variations:
"Kuratowski's intersection theorems" » "Kuratowski's intersection theory", "Kuratowski's interpolation theorems", "Kuratowski's interaction theory", "Kuratowski's intersection theorys", "Kuratowski's interactive theorems", "Kuratowski's interaction theorys"
"kuratowski's interpolation theorem" » "kuratowski's interpolation theory", "kuratowski's interpolation chapter"
"Kuratowski's intersection theorem" » "Kuratowski's intersection theory", "Kuratowski's interactive theorem", "Kuratowski's interaction theory"

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: (((("Kuratowski's intersection theorem") OR ("Kuratowski's intersection theorems"))) OR ("kuratowski's interpolation theorem")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"Kuratowski's intersection theorem\") OR (\"Kuratowski's intersection theorems\"))) or (\"kuratowski's interpolation theorem\"))".
• Removing quotes may allow a broader search: (((( Kuratowski's intersection theorem ) OR ( Kuratowski's intersection theorems ))) or ( kuratowski's interpolation theorem )).
• Adding a wildcard symbol may retrieve word variants: (((("Kuratowski's intersection theorem") OR ("Kuratowski's intersection theorems"))) or ("kuratowski's interpolation theorem"))*.
