Sep 28, 2014 at 15:58 | comment | added | BaoLing | well, if I plug in $T(1)$, then $k=0$, so $x^{-1}$ and $x^{-2}$ vanish. And if I plug in $T(x)$, then $k=1$, so $x^{-1}$ vanishes. and yes, I have checked a few cases, although not all the ones that you suggested, cause the equations become so nasty for $m \ge 4$, that you cannot tell in general, if the eigenvalues are real for all $w$ or not. | |
Sep 28, 2014 at 15:38 | comment | added | Joonas Ilmavirta | Have you checked any cases by hand (or computer)? A numerical check for $2\leq m\leq 10$ will give you a good hint. Also, do you mean $x^{-1}=x^{-2}=0$ in your formula? | |
