I hope I am posting in the right section. I am having a lot of trouble understanding what exactly CW complexes look like. In particular, I am not sure of the definition of an n-cell (in terms of topology, not geometry), and the inductive step of building a CW complex (from X_{n-1} to X_n).(adsbygoogle = window.adsbygoogle || []).push({});

Hope my question makes sense. If anyone has any diagrams to share, that would be invaluable to me. Thanks.
