Perhaps you should try some spelling variations:
"continuous hypothesis" » "continuity hypothesis", "continuous synthesis", "continuum hypotheses"
"continues hypothesis" » "continuity hypothesis", "continuum hypotheses", "constituency hypothesis"
"contact hypothesis" » "continuity hypothesis"
"continuum hypothesis" » "continued hypothesis", "continue hypothesis"

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: (((("continuous hypothesis") OR ("continuum hypothesis"))) OR ((("continues hypothesis") OR ("contact hypothesis")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"continuous hypothesis\") OR (\"continuum hypothesis\"))) or (((\"continues hypothesis\") or (\"contact hypothesis\"))))".
• Removing quotes may allow a broader search: (((( continuous hypothesis ) OR ( continuum hypothesis ))) or ((( continues hypothesis ) or ( contact hypothesis )))).
• Adding a wildcard symbol may retrieve word variants: (((("continuous hypothesis") OR ("continuum hypothesis"))) or ((("continues hypothesis") or ("contact hypothesis"))))*.
