| Nov 25, 2020 at 5:25 | comment | added | LSpice | The ZBM link @FZaldivar mentioned: Vishik - Fields of $u$-invariant $2^r + 1$ (link to article). | |
| Nov 25, 2020 at 2:30 | comment | added | F Zaldivar | A. Vishik has constructed fields with $u$-invariant $2^r+1$ for every $r\geq 3$; see: <a href="zbmath.org/?q=an%3A1236.11037">zbm</a> | |
| Nov 25, 2020 at 2:17 | comment | added | F Zaldivar | T. Y. Lam calls these three cases a "folklore result" and proves them in Propositions 6.8 and 6.9 of his book " Introduction to quadratic forms over fields" (AMS, 2005).. He also remarks that these cases were known before Merkurev's work. Your question is quite interesting. | |

| Nov 25, 2020 at 2:04 | comment | added | Joseph O'Rourke | @FZaldivar: Oh, I see. Yes, that came prior to $u=9$. I will edit the question. Thanks. | |
| Nov 25, 2020 at 2:01 | comment | added | F Zaldivar | According to the review you link to, "It is not difficult to show that $u\neq 3,5,7$" | |
