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