| Nov 6, 2010 at 16:13 | comment | added | Thierry Zell | I would agree with the encyclopaedia criticism, except that in this case, once you ruled out Sturm's theorem and Descartes' rule, there shouldn't be much left. | |
| Nov 6, 2010 at 16:08 | comment | added | Nikita Sidorov | I tend to agree with Willie here. | |
| Nov 6, 2010 at 15:41 | comment | added | J. M. isn't a mathematician | I'm personally fond of using Sturm sequences to generate the (symmetric!) tridiagonal matrix whose characteristic polynomial is the original polynomial. If there is no such matrix, you know at once that the polynomial has complex roots. | |

| Nov 6, 2010 at 15:05 | comment | added | Willie Wong | Also, without further motivation ad clarification, your question is overbroad: please read the FAQ and note the part where it says MO is not an encyclopaedia. | |
