Perhaps you should try some spelling variations:
communication collections » communication applications, communication cohesion, communication foundations
collections methods » collection methods, collocation methods, injections methods
methods dimension » methods diffusion, ethics dimension, metholodgy dimension
whose spaces » phase spaces, shape spaces, whose race
type spaces » state spaces
use spaces » tuple spaces, phase spaces, gauge spaces

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: communication collections methods dimension ((((whose spaces) OR (use spaces))) OR (type spaces))~.
• Adding a wildcard symbol may retrieve word variants: communication collections methods dimension ((((whose spaces) or (use spaces))) or (type spaces))*.
