Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 31 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 31 }$: $ x^{2} + 29 x + 3 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 27 + 10\cdot 31 + 15\cdot 31^{2} + 9\cdot 31^{3} + 19\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 14 a + 18 + \left(14 a + 12\right)\cdot 31 + \left(8 a + 10\right)\cdot 31^{2} + 17\cdot 31^{3} + \left(28 a + 24\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 17 a + 15 + \left(16 a + 27\right)\cdot 31 + \left(22 a + 12\right)\cdot 31^{2} + \left(30 a + 9\right)\cdot 31^{3} + \left(2 a + 18\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 21 a + 27 + 30\cdot 31 + \left(16 a + 26\right)\cdot 31^{2} + \left(27 a + 8\right)\cdot 31^{3} + \left(20 a + 8\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 10 a + 7 + \left(30 a + 11\right)\cdot 31 + \left(14 a + 27\right)\cdot 31^{2} + \left(3 a + 16\right)\cdot 31^{3} + \left(10 a + 22\right)\cdot 31^{4} +O\left(31^{ 5 }\right)$ |
