| Aug 26, 2015 at 10:59 | comment | added | Misha Verbitsky | definitely! thanks for pointing this out, I amended the question | |
| Aug 25, 2015 at 22:48 | comment | added | Anthony Quas | Presumably you want your lattice not to be a multiple of any other lattice? | |
| Aug 25, 2015 at 22:16 | comment | added | Will Jagy | Oh, that probably does demand some kind of diophantine approximation argument, then; I don't quite recall what you commented earlier on the proof you found not really to your liking. | |

| Aug 25, 2015 at 21:38 | comment | added | Misha Verbitsky | Sorry! I misstated the question: I should add an assumption that this 2-dimensional lattice is not definite! | |
| Aug 25, 2015 at 20:48 | comment | added | Will Jagy | seems to me there is a sublattice of dimension $\lceil \frac{n}{2} \rceil$ on which your nondegenerate form is definite. Does that suffice? | |
