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