| Oct 14, 2020 at 21:11 | comment | added | fedja | You should be a bit careful about how you state it because for $a=bk$, the eigenvalue equation factors as $(\lambda-k)(\lambda^2+bk)=0$, which is a borderline case as one would expect only if $k> 0, b>0$. Do you always assume that $a,b,k$ are all positive and are interested in the stability condition under that assumption? | |
