Perhaps you should try some spelling variations:
wiener's criterion » energy criterion
weil's criterion » kelly's criterion, white's criterion, levy's criterion
wiener criteria » wiener criterion, inter criteria, filter criteria
weyl's » well'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 ( weil's criterion ))) OR ((( wiener criteria ) OR ( wiener's criterion )))).
• Adding a wildcard symbol may retrieve word variants: (((( weyl's criterion ) or ( weil's criterion ))) or ((( wiener criteria ) or ( wiener's criterion ))))*.
