Perhaps you should try some spelling variations:
communication communications » communication communication, communication communicating, communications communication
communications case » communication case, communications a, communications _
case dimension » based dimension, fast dimension, scale dimensions
type theorems » type theory
des theorem » eden theorem, rees theorem, davies theorem
pvs theorem » pass theorem, types theorem, axis theorem

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: communication communications case dimension ((des theorem) or (((pvs theorem) or (type theorems))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication communications case dimension ((des theorem) OR (((pvs theorem) OR (type theorems)))).
• Adding a wildcard symbol may retrieve word variants: communication communications case dimension ((des theorem) or (((pvs theorem) or (type theorems))))*.
