| Jun 24, 2013 at 19:43 | comment | added | guest | A is integral, if the minimal polynomial is integral. That means the eigenvalues are integral. Of course, the entries might not be integral. | |

| Jun 23, 2013 at 20:21 | comment | added | user26857 | What eigenvalues? What if the characteristic polynomial has no roots in $R$? | |
