Defining polynomial
$f(x)$ | $=$ | \( x^{5} - x^{4} - 2x^{3} + x + 2 \) . |
The roots of $f$ are computed in an extension of $\Q_{ 19 }$ to precision 5.
Minimal polynomial of a generator $a$ of $K$ over $\mathbb{Q}_{ 19 }$: \( x^{2} + 18x + 2 \)
Roots:
$r_{ 1 }$ | $=$ |
\( 5 a + 4 + \left(7 a + 17\right)\cdot 19 + \left(a + 17\right)\cdot 19^{2} + \left(4 a + 17\right)\cdot 19^{3} + \left(14 a + 9\right)\cdot 19^{4} +O(19^{5})\)
$r_{ 2 }$ |
$=$ |
\( 4 + 17\cdot 19 + 3\cdot 19^{2} + 19^{3} + 13\cdot 19^{4} +O(19^{5})\)
| $r_{ 3 }$ |
$=$ |
\( 3 a + \left(5 a + 10\right)\cdot 19 + \left(18 a + 14\right)\cdot 19^{2} + \left(10 a + 2\right)\cdot 19^{3} + \left(4 a + 10\right)\cdot 19^{4} +O(19^{5})\)

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