Perhaps you should try some spelling variations:
continuous particle » continuous martingales, continuous parameter
continuous posets » continuous sets, continuous process, continuous pareto
continuum » continued, continue, continues
physics » physical

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 posets) OR (continuous particle))) OR (continuum physics)).
• Adding a wildcard symbol may retrieve word variants: ((((continuous posets) or (continuous particle))) or (continuum physics))*.
