Perhaps you should try some spelling variations:
"basic projective a–modules _" » "basic properties a–modules _", "basic projection _–modules _", "basic projective a–modulus _", "basic projective a–nodules _", "basic projective a–models _"
"basic properties a or properties va –modules p" » "basic properties a or properties via –modules p", "basic properties a or properties _ –modules p", "basic properties _ or properties va –modules p", "basic properties via or properties va –modules p", "basic properties a or properties va –modulus _", "basic properties a or properties va –nodules _", "basic properties a or properties va –module 8"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("basic projective a–modules _") or ("basic ((properties a) or (properties va))–modules p"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("basic projective a–modules _") OR ("basic ((properties a) or (properties va))–modules p")).
• Removing quotes may allow a broader search: (( basic projective a–modules _ ) or ( basic ((properties a) or (properties va))–modules p )).
• Adding a wildcard symbol may retrieve word variants: (("basic projective a–modules _") or ("basic ((properties a) or (properties va))–modules p"))*.
