Perhaps you should try some spelling variations:
continuous hypothesis » continuity hypothesis, continuum hypotheses, continuous hyperthermic
continuous synthesis » continuum synthesis, discontinuous synthesis, continents synthesis
continuum » continued, continue, continues

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