Perhaps you should try some spelling variations:
"continuous hypothesis" » "continuum hypothesis", "continuity hypothesis", "continuous synthesis"
"continue hypothesis" » "continuum hypothesis", "continuity hypothesis", "continuum hypotheses"
"continuum synthesis" » "continuous synthesis", "continuum hypothesis", "continents synthesis"

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: (("continue hypothesis") OR ((("continuous hypothesis") OR ("continuum synthesis")))).
• Removing quotes may allow a broader search: (( continue hypothesis ) or ((( continuous hypothesis ) or ( continuum synthesis )))).
• Adding a wildcard symbol may retrieve word variants: (("continue hypothesis") or ((("continuous hypothesis") or ("continuum synthesis"))))*.
