Roots of defining polynomial
The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$: $ x^{2} + 18 x + 2 $
Roots:
| $r_{ 1 }$ |
$=$ |
$ 4 a + 13 + \left(17 a + 18\right)\cdot 19 + \left(12 a + 10\right)\cdot 19^{2} + \left(17 a + 10\right)\cdot 19^{3} + \left(13 a + 4\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 15 a + 9 + \left(9 a + 17\right)\cdot 19 + \left(5 a + 4\right)\cdot 19^{2} + \left(16 a + 6\right)\cdot 19^{3} + \left(13 a + 13\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 9 + 6\cdot 19 + 19^{2} + 12\cdot 19^{3} + 13\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 4 }$ |

| $r_{ 5 }$ |
$=$ |
$ 4 a + 5 + \left(9 a + 12\right)\cdot 19 + 13 a\cdot 19^{2} + \left(2 a + 17\right)\cdot 19^{3} + \left(5 a + 10\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
