What is Spacebook?
How do I use it?
- If your question is “Which spaces have this property, but not that property?”, visit the search page.
- If your question is “Which properties does a particular space possess?”, visit the list page.
Where can I find more information about the spaces and properties?
- Google Books hosts a limited preview of Counterexamples in Topology.
- Wikipedia has articles about many of the spaces.
- Contact the administrator.
How can I contribute?
- Report any incorrect claims you encounter.
- View a space in detail on the list page to see gaps in the database’s knowledge.
- Suggest a new space with a particularly rare combination of properties.
- Suggest an interesting property not appearing in the database.
