| Aug 13, 2017 at 16:08 | comment | added | Suvrit | seems like $0\le t \le 1/2$ could hold, though not yet fully sure. Perhaps the following paper: arxiv.org/abs/1507.00853 sparks some ideas.... | |
| Aug 13, 2017 at 11:41 | comment | added | jjcale | Yes, this is also a counterexample. Next interesting case is $t = 1/2$ . | |
| Aug 12, 2017 at 22:59 | comment | added | Suvrit | Could you verify that $B=\{\{12,-4, 0\},\{-4, 2, 2\},\{0, 2, 8\}\}$ and $R=\{\{-2, -3 ,-2\},\{-3 ,-7,-3\},\{-2, -3, 3\}\}$ for $s=9$ and $t=7/4$ yields a counterexample. | |
| Aug 12, 2017 at 22:41 | comment | added | jjcale | Do you have also a counterexample for $t \le 2$ ? | |
