Kneser did more than sums of squares in that paper. As for Jones, I believe what he did is using Hermite's bound (and a sharper inequality) to deduce that $I_n$ is alone in its genus for $n \leq 7$. | |
| Feb 4, 2016 at 15:01 | comment | added | David Treumann | Thanks for the O'Meara reference. The last footnote on the last page, referring to that Kneser work, is: "See M. Kneser (1957). For an example of the classical approach using 'reduction theory' we refer to BW Jones (1950)." I'd be interested to find out what O'M means, but I didn't find the Jones book yet. | |
