Perhaps you should try some spelling variations:
"local isomorphisms" » "local isomorphism", "local automorphisms"
"local endomorphism" » "local isomorphism", "semilocal endomorphism", "local automorphisms"
"over endomorphism" » "_ endomorphism", "modules endomorphism"

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: (((("local isomorphisms") OR ("local endomorphism"))) OR ("over endomorphism")).
• Removing quotes may allow a broader search: (((( local isomorphisms ) or ( local endomorphism ))) or ( over endomorphism )).
• Adding a wildcard symbol may retrieve word variants: (((("local isomorphisms") or ("local endomorphism"))) or ("over endomorphism"))*.
