| Aug 6, 2020 at 20:42 | comment | added | march | Apparently there is something called the Jury stability criterion which you can use to determine if the roots of a polynomial are all inside the unit disk. | |
| Aug 6, 2020 at 20:34 | comment | added | march | I assume that by $S^1$ you mean that unit circle in the complex plane? So you are allowing complex roots? Just for clarification. | |
| Aug 6, 2020 at 18:08 | comment | added | flinty | If you have a function roots that gets the roots of a polynomial into a list form of consistent dimension, then why not something like: Select[polys, Not[0!=Norm[roots[#]]!=1] &] | |
