| Aug 13, 2014 at 13:23 | comment | added | Jim Humphreys | @IMeasy: You should also make your notation $\mathbb{Z}_2$ clear, since it can mean two things. Is this what the tag 'finite-fields' is for? | |
| Aug 13, 2014 at 13:22 | comment | added | IMeasy | no, I am sorry, I should have explained. By even and odd I mean the Arf invariant of a quadratic form on a $\mathbb{Z}_2$-vector space. I will correct the question. | |
