| Nov 12, 2010 at 22:21 | comment | added | j.c. | @Kimball, as you no doubt know, (2n+1)-dimensional real projective spaces are orientable, as are all complex projective spaces. I don't know how to think about orientability for finite projective spaces. | |
| Nov 12, 2010 at 22:00 | comment | added | Kimball | Also, projective spaces are very important in algebraic geometry, and finite projective spaces are a big topic in coding theory and design theory. Finite spaces are of course not manifolds, but this is an example of the application of the development of certain non-orientable spaces. | |
