Talvez debería tentar con algunhas variantes ortográficas:
basics dspaces » basic spaces, basic space
basics spaces » basics sources, basics series, based spaces
based dspaces » based spaces, based space, based distances
dspaces » ddspaces
spaces » dspaces
space » dspace

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: information its ((((basics dspaces) OR (basics spaces))) OR (based dspaces)) euclidean space~.
• Adding a wildcard symbol may retrieve word variants: information its ((((basics dspaces) or (basics spaces))) or (based dspaces)) euclidean space*.
