Perhaps you should try some spelling variations:
"duarte's criterion" » "squares criterion", "cartan's criterion", "lane's criterion"
"weil's criterion" » "kelly's criterion", "white's criterion", "levy's criterion"
"wiener criterion" » "wiener's criterion", "wiener criteria", "fisher criterion"
"weyl's criterion" » "well's criterion"

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 ((("weil's criterion") OR ("duarte's criterion"))))) OR ("wiener criterion")).
• Removing quotes may allow a broader search: (((( weyl's criterion ) or ((( weil's criterion ) or ( duarte's criterion ))))) or ( wiener criterion )).
• Adding a wildcard symbol may retrieve word variants: (((("weyl's criterion") or ((("weil's criterion") or ("duarte's criterion"))))) or ("wiener criterion"))*.
