Perhaps you should try some spelling variations:
linker's criteria » funder's criteria, concerns criteria, line criteria
levy's criterion » kelly's criterion, lane's criterion, level criterion
li's criterion » lms criterion, ls criterion, lane's criterion
weyl's » well's, weil's

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: (((( weyl's criterion ) OR ((( li's criterion ) OR ( levy's criterion ))))) OR ( linker's criteria )).
• Adding a wildcard symbol may retrieve word variants: (((( weyl's criterion ) or ((( li's criterion ) or ( levy's criterion ))))) or ( linker's criteria ))*.
