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