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:
| $r_{ 1 }$ |
$=$ |
$ 13 a + \left(9 a + 11\right)\cdot 19 + \left(7 a + 4\right)\cdot 19^{2} + \left(8 a + 7\right)\cdot 19^{3} + \left(18 a + 12\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 2 }$ |
$=$ |
$ 6 a + 13 + \left(9 a + 7\right)\cdot 19 + \left(11 a + 2\right)\cdot 19^{2} + \left(10 a + 8\right)\cdot 19^{3} + 3\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 3 }$ |
$=$ |
$ 7 + 12\cdot 19^{2} + 3\cdot 19^{3} + 3\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 4 }$ |
$=$ |
$ 16 a + 18 + \left(10 a + 3\right)\cdot 19 + \left(8 a + 6\right)\cdot 19^{2} + 12\cdot 19^{3} + \left(6 a + 14\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 5 }$ |
$=$ |
$ 6 + 16\cdot 19 + 8\cdot 19^{2} + 2\cdot 19^{3} + 3\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
| $r_{ 6 }$ |
$=$ |
$ 3 a + 15 + \left(8 a + 17\right)\cdot 19 + \left(10 a + 3\right)\cdot 19^{2} + \left(18 a + 4\right)\cdot 19^{3} + \left(12 a + 1\right)\cdot 19^{4} +O\left(19^{ 5 }\right)$ |
